FileMailer Class
Properties Methods Events Config Settings Errors
The FileMailer Class is used to send emails with file attachments.
Syntax
FileMailer
Remarks
The FileMailer Class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections (RFC 2487). When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.
The class sends a message (provided in MessageText) and one or more file attachments specified in the Attachments properties.
The recipients are specified by the SendTo, Cc, and BCc properties, and the message subject is specified by the Subject property.
After all of the appropriate properties have been set, call the Send method and your message will be sent to its intended recipients.
Other SMTP headers may be specified through the OtherHeaders property. Information about interaction with the server is provided through the PITrail event.

int ipworks_filemailer_setauthmechanism(void* lpObj, int iAuthMechanism);
int GetAuthMechanism();
int SetAuthMechanism(int iAuthMechanism);
Default Value
0
Remarks
This is the authentication mechanism property to be used when connecting to the mail server.
By default, this property is amUserPassword (0), and if the User and Password properties are set, the AUTH command is sent to the server for authentication. If this property is set to amCRAMMD5 (1), CRAM-MD5 authentication is used instead.
If this property is set to amNTLM (2), NTLM authentication will be used.
If this property is set to amKerberos (6), Kerberos authentication will be used.
Note: This functionality is available only in Windows.
When set to amXOAUTH2 (7), set User to the username and AuthorizationIdentity to the OAuth token. See AuthorizationIdentity for details.
Data Type
Integer
BCc Property (FileMailer Class)
This property includes a comma-separated list of addresses for blind carbon copies (optional).
Syntax
ANSI (Cross Platform) char* GetBCc();
int SetBCc(const char* lpszBCc); Unicode (Windows) LPWSTR GetBCc();
INT SetBCc(LPCWSTR lpszBCc);
char* ipworks_filemailer_getbcc(void* lpObj);
int ipworks_filemailer_setbcc(void* lpObj, const char* lpszBCc);
QString GetBCc();
int SetBCc(QString qsBCc);
Default Value
""
Remarks
This property specifies a comma-separated list of destinations for blind carbon copies of the mail message. A copy of the message is sent to each destination. Because no BCc SMTP header is created containing the destination addresses, individual recipients never see the list of the other recipients.
The class will return an error if the MailServer returns an error code about any email address specified in SendTo or Cc but it will fire an Error event only if the same thing happens with an email address specified in this property.
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
Note: You must clear the MessageRecipients properties before setting this property to remove previous recipients.
Data Type
String
Cc Property (FileMailer Class)
This property includes a comma-separated list of addresses for carbon copies (optional).
Syntax

char* ipworks_filemailer_getcc(void* lpObj);
int ipworks_filemailer_setcc(void* lpObj, const char* lpszCc);
QString GetCc();
int SetCc(QString qsCc);
Default Value
""
Remarks
This property specifies a comma-separated list of destinations for carbon copies of the mail message. A copy of the message is sent to each destination, and a Cc SMTP header is created containing the destination addresses. This header is sent to every recipient of the message. If you don't want to copy this information to every recipient, then use blind carbon copies instead (see the description of the BCc).
The class will return an error if the MailServer returns an error code about any email address specified in SendTo or Cc but it will fire an Error event only if the same thing happens with an email address specified in BCc.
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
Note: You must clear the MessageRecipients properties before setting this property to remove previous recipients.
Data Type

char* ipworks_filemailer_getlastreply(void* lpObj);
QString GetLastReply();
Default Value
""
Remarks
This property indicates the last reply received from the server. It can be used for informational purposes. The same information and more also can be retrieved through the PITrail event.
This property is read-only.
Data Type
String
LocalHost Property (FileMailer Class)
This property includes the name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
ANSI (Cross Platform) char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost); Unicode (Windows) LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);
char* ipworks_filemailer_getlocalhost(void* lpObj);
int ipworks_filemailer_setlocalhost(void* lpObj, const char* lpszLocalHost);
QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);
Default Value
""
Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.
If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Note: LocalHost is not persistent. You must always set it in code, and never in the property window.
Data Type
String
MailPort Property (FileMailer Class)
This property includes the server port for SMTP (default 25).
Syntax
ANSI (Cross Platform) int GetMailPort();
int SetMailPort(int iMailPort); Unicode (Windows) INT GetMailPort();

int ipworks_filemailer_getmailport(void* lpObj);
int ipworks_filemailer_setmailport(void* lpObj, int iMailPort);
int GetMailPort();
int SetMailPort(int iMailPort);
Default Value
25
Remarks
This property contains the server port for SMTP (default 25). A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.
For an implicit Secure Sockets Layer (SSL), use port 465 (please refer to the SSLStartMode property for more information).
This property is not available at design time.
Data Type
Integer
MailServer Property (FileMailer Class)
This property includes the name or address of a mail server (mail relay).
Syntax
ANSI (Cross Platform) char* GetMailServer();
int SetMailServer(const char* lpszMailServer); Unicode (Windows) LPWSTR GetMailServer();
INT SetMailServer(LPCWSTR lpszMailServer);
char* ipworks_filemailer_getmailserver(void* lpObj);
int ipworks_filemailer_setmailserver(void* lpObj, const char* lpszMailServer);
QString GetMailServer();
int SetMailServer(QString qsMailServer);
Default Value
""
Remarks
This property specifies the IP address (IP number in dotted internet format) or domain name for a mail relay through which messages will be routed. It is set before a connection is attempted and cannot be changed once a connection is in progress.
The current version of the class does not provide a default value for the mail relay. You must provide a host name yourself. Generally, any internet host with an SMTP server will suffice (e.g., a UNIX host), but it is preferable to select a MailServer that is close to the machine sending mail.
If this property is set to a domain name, a DNS request is initiated. Upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.
If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.
Data Type
String
MessageDate Property (FileMailer Class)
This property includes the date of the mail message (optional).
Syntax
ANSI (Cross Platform) char* GetMessageDate();
int SetMessageDate(const char* lpszMessageDate); Unicode (Windows) LPWSTR GetMessageDate();

char* ipworks_filemailer_getmessagedate(void* lpObj);
int ipworks_filemailer_setmessagedate(void* lpObj, const char* lpszMessageDate);
QString GetMessageDate();
int SetMessageDate(QString qsMessageDate);
Default Value
"*"
Remarks
If this property contains a nonempty string, then a Date SMTP header is created and attached to the message. If it is an empty string, then the date information is added by the mail relay(s) the message goes through.
Special case: If this property is set to the special value "*", a Date SMTP header reflecting the current date and time is generated when MessageHeaders is computed and the message is sent. This is the default behavior of the class
RFC 822 contains detailed date format specifications. An example of a valid date is "Fri, 1 Mar 96 21:24:52 EST".
This property is not available at design time.
Data Type
String
MessageId Property (FileMailer Class)

int ipworks_filemailer_setmessageid(void* lpObj, const char* lpszMessageId);
QString GetMessageId();
int SetMessageId(QString qsMessageId);
Default Value
"*"
Remarks
This property contains the message identifier for the message. When set, the value of MessageId is used as the Message-Id header value of the message. A special value of "*" will automatically generate a random unique identifier for the message.
This property is not available at design time.

This property contains a collection that describes to whom the message is being sent. You may include all recipients in this property, even Cc's and BCc's, which are specified by the type field.
Data Type
MessageText Property (FileMailer Class)
This is the full text of the message to send (without headers).
Syntax
ANSI (Cross Platform) char* GetMessageText();
int SetMessageText(const char* lpszMessageText); Unicode (Windows) LPWSTR GetMessageText();
INT SetMessageText(LPCWSTR lpszMessageText);
char* ipworks_filemailer_getmessagetext(void* lpObj);
int ipworks_filemailer_setmessagetext(void* lpObj, const char* lpszMessageText);
QString GetMessageText();
int SetMessageText(QString qsMessageText);
Default Value
""
Remarks
This property contains the full text of the message.
The text contained in this property should be a collection of lines with lengths less than or equal to 80 bytes separated by CRLF ("\r\n") . The text in the message lines must contain 7-bit characters so that the message can successfully pass through the multitude of mail systems on the internet.
The class automatically escapes lines that start with a "." by adding another as specified in RFC 821. The message text is unescaped by the receiving agent, so the process is fully transparent.
Data Type
String
OtherHeaders Property (FileMailer Class)
This property includes an RFC 822-compliant string consisting of extra headers.
Syntax
ANSI (Cross Platform) char* GetOtherHeaders();
int SetOtherHeaders(const char* lpszOtherHeaders); Unicode (Windows) LPWSTR GetOtherHeaders();
INT SetOtherHeaders(LPCWSTR lpszOtherHeaders);
char* ipworks_filemailer_getotherheaders(void* lpObj);
int ipworks_filemailer_setotherheaders(void* lpObj, const char* lpszOtherHeaders);
QString GetOtherHeaders();
int SetOtherHeaders(QString qsOtherHeaders);
Default Value
""
Remarks
This property contains a string of headers to be appended to the message headers created from other properties like SendTo, Subject, and so on.
The headers must be of the format "header: value" as specified in RFC 822. Header lines should be separated by CRLF ("\r\n") .
Use this property with caution. If this property contains invalid headers, message delivery might not be successful.
This property is useful for extending the functionality of the class. A good example is delivery of MIME-encoded messages.
Special case: If this property starts with an empty line (CRLF), then the value of this property is used instead of the normally computed message headers.
Example. Sending an Email with an Additional Header:
component.MailServer = "MyServer";
component.From = "me@server.com";
component.SendTo = "recipient@server.com";
component.Subject = "My Subject";
component.MessageText = "This is the message body.";
component.OtherHeaders = "HeaderName: HeaderValue";
component.Send();
This property is not available at design time.

char* ipworks_filemailer_getpassword(void* lpObj);
int ipworks_filemailer_setpassword(void* lpObj, const char* lpszPassword);
QString GetPassword();
int SetPassword(QString qsPassword);
Default Value
""
Remarks
If this property is set to a nonempty string, then when connecting to the MailServer an AUTH or CRAM-MD5 (depending on the value of AuthMechanism) command is sent to provide authentication information for the user.
This property is not available at design time.
Data Type
String

int ipworks_filemailer_getpriority(void* lpObj);
int ipworks_filemailer_setpriority(void* lpObj, int iPriority);
int GetPriority();
int SetPriority(int iPriority);
Default Value
0
Remarks
When this property is set, a priority header will be added to the message. Priority is an indication about the delivery priority of the message. The possible values are epNormal, epUrgent, and epNonUrgent.
Data Type
Integer
ReadReceiptTo Property (FileMailer Class)
This property includes the email address to send a read-receipt to.
Syntax
ANSI (Cross Platform) char* GetReadReceiptTo();
int SetReadReceiptTo(const char* lpszReadReceiptTo); Unicode (Windows) LPWSTR GetReadReceiptTo();

Data Type
String
ReplyTo Property (FileMailer Class)
This property includes a mail address to which to reply (optional).
Syntax
ANSI (Cross Platform) char* GetReplyTo();
int SetReplyTo(const char* lpszReplyTo); Unicode (Windows) LPWSTR GetReplyTo();
INT SetReplyTo(LPCWSTR lpszReplyTo);
char* ipworks_filemailer_getreplyto(void* lpObj);
int ipworks_filemailer_setreplyto(void* lpObj, const char* lpszReplyTo);
QString GetReplyTo();
int SetReplyTo(QString qsReplyTo);
Default Value
""
Remarks
If this property contains a nonempty string, a Reply-To SMTP header is created for the message. This header shows the address to use for replies, which is useful if this address is different from the one in From.
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
Data Type
String
SendTo Property (FileMailer Class)
This property includes a comma-separated list of addresses for destinations (required).
Syntax
ANSI (Cross Platform) char* GetSendTo();
int SetSendTo(const char* lpszSendTo); Unicode (Windows) LPWSTR GetSendTo();
INT SetSendTo(LPCWSTR lpszSendTo);
char* ipworks_filemailer_getsendto(void* lpObj);
int ipworks_filemailer_setsendto(void* lpObj, const char* lpszSendTo);
QString GetSendTo();
int SetSendTo(QString qsSendTo);
Default Value
""
Remarks
This property specifies a comma-separated list of destinations for the mail message. A copy of the message is sent to each of them, and a To SMTP header is created containing the destination addresses.
Examples of valid addresses are as follows: "Friendly Name" <address@company.com> or address@company.com
The class will fail if the MailServer returns an error code about any email address specified in SendTo or Cc but it will silently ignore the error if the same thing happens with an email address specified in BCc.
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
Note: You must clear the MessageRecipients properties before setting this property to remove previous recipients.
Data Type
String

int SetSSLAcceptServerCertSubject(QString qsSSLAcceptServerCertSubject); QByteArray GetSSLAcceptServerCertEncoded();
int SetSSLAcceptServerCertEncoded(QByteArray qbaSSLAcceptServerCertEncoded);
Remarks
If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.
You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.
Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.
Data Type
SSLCert Property (FileMailer Class)
This property includes the certificate to be used during Secure Sockets Layer (SSL) negotiation.

Remarks
This property includes the digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.
Data Type
SSLEnabled Property (FileMailer Class)
This property indicates whether Transport Layer Security/Secure Sockets Layer (TLS/SSL) is enabled.
Syntax
ANSI (Cross Platform) int GetSSLEnabled();
int SetSSLEnabled(int bSSLEnabled); Unicode (Windows) BOOL GetSSLEnabled();
INT SetSSLEnabled(BOOL bSSLEnabled);
int ipworks_filemailer_getsslenabled(void* lpObj);
int ipworks_filemailer_setsslenabled(void* lpObj, int bSSLEnabled);
bool GetSSLEnabled();
int SetSSLEnabled(bool bSSLEnabled);
Default Value
FALSE
Remarks
This property specifies whether TLS/SSL is enabled in the class. When False (default), the class operates in plaintext mode. When True, TLS/SSL is enabled.
TLS/SSL may also be enabled by setting SSLStartMode. Setting SSLStartMode will automatically update this property value.
This property is not available at design time.
Data Type
Boolean
SSLProvider Property (FileMailer Class)
This property specifies the Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.
Syntax
ANSI (Cross Platform) int GetSSLProvider();
int SetSSLProvider(int iSSLProvider); Unicode (Windows) INT GetSSLProvider();
INT SetSSLProvider(INT iSSLProvider);
Possible Values
SSLP_AUTOMATIC(0),
SSLP_PLATFORM(1),
SSLP_INTERNAL(2)
int ipworks_filemailer_getsslprovider(void* lpObj);
int ipworks_filemailer_setsslprovider(void* lpObj, int iSSLProvider);
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are as follows:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.
When Automatic is selected, on Windows, the class will use the platform implementation. On Linux/macOS, the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used on all platforms.
Data Type
Integer
SSLServerCert Property (FileMailer Class)
This property includes the server certificate for the last established connection.
Syntax

Data Type
SSLStartMode Property (FileMailer Class)
This property determines how the class starts the Secure Sockets Layer (SSL) negotiation.
Syntax
ANSI (Cross Platform) int GetSSLStartMode();
int SetSSLStartMode(int iSSLStartMode); Unicode (Windows) INT GetSSLStartMode();
INT SetSSLStartMode(INT iSSLStartMode);
Possible Values
SSL_AUTOMATIC(0),

int ipworks_filemailer_setsslstartmode(void* lpObj, int iSSLStartMode);
int GetSSLStartMode();
int SetSSLStartMode(int iSSLStartMode);
Default Value
3
Remarks
The SSLStartMode property may have one of the following values:
0 (sslAutomatic) | If the remote port is set to the standard plaintext port of the protocol (where applicable), the class will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit). |
1 (sslImplicit) | The SSL negotiation will start immediately after the connection is established. |
2 (sslExplicit) | The class will first connect in plaintext, and then will explicitly start SSL negotiation through a protocol command such as STARTTLS. |
3 (sslNone - default) | No SSL negotiation; no SSL security. All communication will be in plaintext mode. |
Data Type
Integer
Subject Property (FileMailer Class)
This property includes the subject of the mail message (optional).
Syntax
ANSI (Cross Platform) char* GetSubject();
int SetSubject(const char* lpszSubject); Unicode (Windows) LPWSTR GetSubject();
INT SetSubject(LPCWSTR lpszSubject);
char* ipworks_filemailer_getsubject(void* lpObj);
int ipworks_filemailer_setsubject(void* lpObj, const char* lpszSubject);
QString GetSubject();
int SetSubject(QString qsSubject);
Default Value
""
Remarks
The string in this property is sent with a Subject SMTP header to the mail recipient.
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
Data Type
String
Timeout Property (FileMailer Class)
This property includes the timeout for the class.
Syntax
ANSI (Cross Platform) int GetTimeout();
int SetTimeout(int iTimeout); Unicode (Windows) INT GetTimeout();
INT SetTimeout(INT iTimeout);
int ipworks_filemailer_gettimeout(void* lpObj);
int ipworks_filemailer_settimeout(void* lpObj, int iTimeout);
int GetTimeout();
int SetTimeout(int iTimeout);
Default Value
60
Remarks
If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.
If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.
The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.
If Timeout expires, and the operation is not yet complete, the class fails with an error.
Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.
Data Type
Integer
User Property (FileMailer Class)
This property includes the user identifier needed to log in as in the MailServer .
Syntax
ANSI (Cross Platform) char* GetUser();
int SetUser(const char* lpszUser); Unicode (Windows) LPWSTR GetUser();
INT SetUser(LPCWSTR lpszUser);
char* ipworks_filemailer_getuser(void* lpObj);
int ipworks_filemailer_setuser(void* lpObj, const char* lpszUser);
QString GetUser();
int SetUser(QString qsUser);
Default Value
""
Remarks
If this property is set to a nonempty string, then when connecting to the MailServer an AUTH or CRAM-MD5 (depending on the value of AuthMechanism) command is sent to provide authentication information for the user.
This property is not available at design time.
Data Type
String
AddAttachment Method (FileMailer Class)
This adds FileName as an attachment.
Syntax
ANSI (Cross Platform) int AddAttachment(const char* lpszFileName); Unicode (Windows) INT AddAttachment(LPCWSTR lpszFileName);
int ipworks_filemailer_addattachment(void* lpObj, const char* lpszFileName);
int AddAttachment(const QString& qsFileName);
Remarks
This method adds the file name as an attachment. The full list of attachments is contained in the Attachments property.
Example 1: Adding an Attachment
component.AddAttachment("C:\file1.zip");
component.AddAttachment("C:\file2.zip");
component.Send();
Example 3: Using an Attachments Array
component.AttachmentCount = 1;
component.AttachmentName(0) = "name";
component.AttachmentFile(0) = "C:\file.txt";
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Config Method (FileMailer Class)
Sets or retrieves a configuration setting.
Syntax
ANSI (Cross Platform) char* Config(const char* lpszConfigurationString); Unicode (Windows) LPWSTR Config(LPCWSTR lpszConfigurationString);
char* ipworks_filemailer_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
Connect Method (FileMailer Class)
This method connects to the mail relay and sends the SMTP HELO command.
Syntax
ANSI (Cross Platform) int Connect(); Unicode (Windows) INT Connect();
int ipworks_filemailer_connect(void* lpObj);

int ipworks_filemailer_disconnect(void* lpObj);
int Disconnect();
Remarks
This method disconnects from the mail relay.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
DoEvents Method (FileMailer Class)
This method processes events from the internal message queue.
Syntax
ANSI (Cross Platform) int DoEvents(); Unicode (Windows) INT DoEvents();
int ipworks_filemailer_doevents(void* lpObj);
int DoEvents();
Remarks
When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Interrupt Method (FileMailer Class)
This method interrupts the current method.
Syntax
ANSI (Cross Platform) int Interrupt(); Unicode (Windows) INT Interrupt();

int Interrupt();
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
ProcessQueue Method (FileMailer Class)
This method sends the messages that previously have been queued into QueueDir .
Syntax
ANSI (Cross Platform) int ProcessQueue(const char* lpszQueueDir); Unicode (Windows) INT ProcessQueue(LPCWSTR lpszQueueDir);
int ipworks_filemailer_processqueue(void* lpObj, const char* lpszQueueDir);
int ProcessQueue(const QString& qsQueueDir);
Remarks
This method sends the messages that previously have been queued into QueueDir. The PITrail event shows the interaction with the server as messages are processed.
This method looks in the directory for files with the extension ".queued" and starts processing them.
When processing starts, the file extension is changed to ".sending". If an error happens at this stage, the sending process is aborted, and the file extension is changed to ".failed".
If the file is successfully sent, the file is normally deleted, unless the KeepQueue configuration setting is set to True, in which case the file extension is instead changed to ".sent" and the queue file is not deleted.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Queue Method (FileMailer Class)
This method queues the message into QueueDir .
Syntax

char* ipworks_filemailer_queue(void* lpObj, const char* lpszQueueDir);
QString Queue(const QString& qsQueueDir);
Remarks
This method queues the message into QueueDir. The message is queued into a unique file into the directory QueueDir for future processing.
QueueDir must already exist, or an error will be generated. Alternatively, QueueDir may be set to "*" to return the result as a string instead of writing it to a file.
This method returns the name of the unique queue file created in QueueDir. The file extension is ".queued".
Please refer to the ProcessQueue method for more information on email queue processing.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Send Method (FileMailer Class)
This sends the current message and the MIME-encoded attachment.
Syntax
ANSI (Cross Platform) int Send(); Unicode (Windows) INT Send();
int ipworks_filemailer_send(void* lpObj);
int Send();
Remarks
This method sends the current message and the MIME-encoded attachment. If the class is not connected to the mail relay, a connection is created, the message is sent, and then the connection is closed unless an error occurs.
If the class is already connected (by use of the Connect method), the connection will remain open after the message is sent. To disconnect, call the Disconnect method.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

int ipworks_filemailer_sendcommand(void* lpObj, const char* lpszCommand);
int SendCommand(const QString& qsCommand);
Remarks
This method sends the command specified by Command to the server exactly as it is provided. Use this method to send additional or custom commands directly to the server.
After calling this method, check the LastReply property or monitor the PITrail event to obtain the server's response.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
SetMessageStream Method (FileMailer Class)
This method sets the stream to be uploaded to the server as part of the message.
Syntax
ANSI (Cross Platform) int SetMessageStream(IPWorksStream* sMessageStream); Unicode (Windows) INT SetMessageStream(IPWorksStream* sMessageStream);
int ipworks_filemailer_setmessagestream(void* lpObj, IPWorksStream* sMessageStream);
int SetMessageStream(IPWorksStream* sMessageStream);
Remarks
This method sets the stream to be uploaded to the server as part of the message. If an upload stream is set before the Send method is called, the content of the stream will be read by the class and uploaded to the server. The stream should be open and normally set to position 0. The class will automatically close this stream if CloseStreamAfterTransfer is set to True (default). If the stream is closed, you will need to call this method again before calling Send again. The content of the stream will be read from the current position all the way to the end.
Note: This method and LocalFile will reset the other.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
ConnectionStatus Event (FileMailer Class)
This event is fired to indicate changes in the connection state.
Syntax
ANSI (Cross Platform) virtual int FireConnectionStatus(FileMailerConnectionStatusEventParams *e);
typedef struct {
const char *ConnectionEvent;
int StatusCode;
const char *Description; int reserved; } FileMailerConnectionStatusEventParams;
Unicode (Windows) virtual INT FireConnectionStatus(FileMailerConnectionStatusEventParams *e);
typedef struct {
LPCWSTR ConnectionEvent;
INT StatusCode;
LPCWSTR Description; INT reserved; } FileMailerConnectionStatusEventParams;
#define EID_FILEMAILER_CONNECTIONSTATUS 1 virtual INT IPWORKS_CALL FireConnectionStatus(LPSTR &lpszConnectionEvent, INT &iStatusCode, LPSTR &lpszDescription);
class FileMailerConnectionStatusEventParams { public: const QString &ConnectionEvent(); int StatusCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void ConnectionStatus(FileMailerConnectionStatusEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FireConnectionStatus(FileMailerConnectionStatusEventParams *e) {...}
Remarks
The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.
The ConnectionEvent parameter indicates the type of connection event. Values may include the following:
Firewall connection complete. | |
Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | |
Remote host connection complete. | |
Remote host disconnected. | |
SSL or S/Shell connection broken. | |
Firewall host disconnected. |
EndTransfer Event (FileMailer Class)
This event is fired when the message text completes transferring.
Syntax
ANSI (Cross Platform) virtual int FireEndTransfer(FileMailerEndTransferEventParams *e);
typedef struct {
int Direction; int reserved; } FileMailerEndTransferEventParams;
Unicode (Windows) virtual INT FireEndTransfer(FileMailerEndTransferEventParams *e);
typedef struct {
INT Direction; INT reserved; } FileMailerEndTransferEventParams;
#define EID_FILEMAILER_ENDTRANSFER 2 virtual INT IPWORKS_CALL FireEndTransfer(INT &iDirection);
class FileMailerEndTransferEventParams { public: int Direction(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void EndTransfer(FileMailerEndTransferEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FireEndTransfer(FileMailerEndTransferEventParams *e) {...}
Remarks
If MessageText is not empty, the EndTransfer event is fired when the MessageText finishes transferring from the local host to the MailServer. If MessageText is empty, the event is not fired.
If a file is attached to the MessageText via the AttachedFile property, then EndTransfer fires again when the file finishes transferring. For more information, go to the description of the AttachedFile property.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Error Event (FileMailer Class)
Fired when information is available about errors during data delivery.
Syntax
ANSI (Cross Platform) virtual int FireError(FileMailerErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } FileMailerErrorEventParams;
Unicode (Windows) virtual INT FireError(FileMailerErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } FileMailerErrorEventParams;
#define EID_FILEMAILER_ERROR 3 virtual INT IPWORKS_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class FileMailerErrorEventParams { public: int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Error(FileMailerErrorEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FireError(FileMailerErrorEventParams *e) {...}
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.
The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
PITrail Event (FileMailer Class)
This event traces the commands sent to the mail server, and the respective replies.
Syntax
ANSI (Cross Platform) virtual int FirePITrail(FileMailerPITrailEventParams *e);
typedef struct {
int Direction;
const char *Message; int reserved; } FileMailerPITrailEventParams;
Unicode (Windows) virtual INT FirePITrail(FileMailerPITrailEventParams *e);
typedef struct {
INT Direction;
LPCWSTR Message; INT reserved; } FileMailerPITrailEventParams;
#define EID_FILEMAILER_PITRAIL 4 virtual INT IPWORKS_CALL FirePITrail(INT &iDirection, LPSTR &lpszMessage);
class FileMailerPITrailEventParams { public: int Direction(); const QString &Message(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void PITrail(FileMailerPITrailEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FirePITrail(FileMailerPITrailEventParams *e) {...}
Remarks
The PITrail event is useful for debugging purposes. It shows all of the interaction between the client and the server, line by line, except for message header and body transfers.
The Message parameter contains the full text of the message. The Direction parameter shows the originator of the message:
0 (Client) | The Message originates from the client. |
1 (Server) | The Message originates from the server. |
2 (Info) | The Message is an informative message originating from the client software (the class code). |
SSLServerAuthentication Event (FileMailer Class)
Fired after the server presents its certificate to the client.
Syntax
ANSI (Cross Platform) virtual int FireSSLServerAuthentication(FileMailerSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;
const char *Status;
int Accept; int reserved; } FileMailerSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(FileMailerSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;
LPCWSTR Status;
BOOL Accept; INT reserved; } FileMailerSSLServerAuthenticationEventParams;
#define EID_FILEMAILER_SSLSERVERAUTHENTICATION 5 virtual INT IPWORKS_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);
class FileMailerSSLServerAuthenticationEventParams { public: const QByteArray &CertEncoded(); const QString &CertSubject(); const QString &CertIssuer(); const QString &Status(); bool Accept(); void SetAccept(bool bAccept); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void SSLServerAuthentication(FileMailerSSLServerAuthenticationEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FireSSLServerAuthentication(FileMailerSSLServerAuthenticationEventParams *e) {...}
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (FileMailer Class)
Fired when secure connection progress messages are available.
Syntax
ANSI (Cross Platform) virtual int FireSSLStatus(FileMailerSSLStatusEventParams *e);
typedef struct {
const char *Message; int reserved; } FileMailerSSLStatusEventParams;
Unicode (Windows) virtual INT FireSSLStatus(FileMailerSSLStatusEventParams *e);
typedef struct {
LPCWSTR Message; INT reserved; } FileMailerSSLStatusEventParams;
#define EID_FILEMAILER_SSLSTATUS 6 virtual INT IPWORKS_CALL FireSSLStatus(LPSTR &lpszMessage);
class FileMailerSSLStatusEventParams { public: const QString &Message(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void SSLStatus(FileMailerSSLStatusEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FireSSLStatus(FileMailerSSLStatusEventParams *e) {...}
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
StartTransfer Event (FileMailer Class)
This event is fired when the message text starts transferring.
Syntax
ANSI (Cross Platform) virtual int FireStartTransfer(FileMailerStartTransferEventParams *e);
typedef struct {
int Direction; int reserved; } FileMailerStartTransferEventParams;
Unicode (Windows) virtual INT FireStartTransfer(FileMailerStartTransferEventParams *e);
typedef struct {
INT Direction; INT reserved; } FileMailerStartTransferEventParams;
#define EID_FILEMAILER_STARTTRANSFER 7 virtual INT IPWORKS_CALL FireStartTransfer(INT &iDirection);
class FileMailerStartTransferEventParams { public: int Direction(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void StartTransfer(FileMailerStartTransferEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FireStartTransfer(FileMailerStartTransferEventParams *e) {...}
Remarks
If MessageText is not empty, the StartTransfer event is fired when the MessageText starts transferring from the local host to the MailServer. If MessageText is empty, the event is not fired.
If a file is attached to the MessageText via the AttachedFile property, then StartTransfer fires again when the file starts transferring. Please go to the description of the AttachedFile property for more information.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Transfer Event (FileMailer Class)
This event is fired when the message text is transferred to MailServer .
Syntax
ANSI (Cross Platform) virtual int FireTransfer(FileMailerTransferEventParams *e);
typedef struct {
int Direction;
int64 BytesTransferred;
int PercentDone;
const char *Text; int lenText; int reserved; } FileMailerTransferEventParams;
Unicode (Windows) virtual INT FireTransfer(FileMailerTransferEventParams *e);
typedef struct {
INT Direction;
LONG64 BytesTransferred;
INT PercentDone;
LPCSTR Text; INT lenText; INT reserved; } FileMailerTransferEventParams;
#define EID_FILEMAILER_TRANSFER 8 virtual INT IPWORKS_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText);
class FileMailerTransferEventParams { public: int Direction(); qint64 BytesTransferred(); int PercentDone(); const QByteArray &Text(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Transfer(FileMailerTransferEventParams *e);
// Or, subclass FileMailer and override this emitter function. virtual int FireTransfer(FileMailerTransferEventParams *e) {...}
Remarks
One or more Transfer events are fired during message delivery. Messages consist of MessageText and an optional AttachedFile. The BytesTransferred parameter shows the number of bytes sent starting from the beginning of MessageText or AttachedFile.
Text contains the current portion of the message being sent.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.
Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

22 (cstBCFKSBlob) | The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format.
Note: This store type is only available in Java and .NET. |
23 (cstPKCS11) | The certificate is present on a physical security key accessible via a PKCS#11 interface.
To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN. Code Example. SSH Authentication with Security Key:
|
99 (cstAuto) | The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically. |

- CRL Signing
- Encipher Only
If the provider is OpenSSL, the value is a comma-separated list of X.509 certificate extension names.
UsageFlags
int (read-only)
Default Value: 0
This field contains the flags that show intended use for the certificate. The value of UsageFlags is a combination of the following flags:
0x80 | Digital Signature |
0x40 | Non-Repudiation |
0x20 | Key Encipherment |
0x10 | Data Encipherment |
0x08 | Key Agreement |
0x04 | Certificate Signing |
0x02 | CRL Signing |
0x01 | Encipher Only |
Please see the Usage field for a text representation of UsageFlags.
This functionality currently is not available when the provider is OpenSSL.
Version
char* (read-only)
Default Value: ""
This field contains the certificate's version number. The possible values are the strings "V1", "V2", and "V3".
Subject
char*
Default Value: ""
This is the subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the field is set to the full subject of the matching certificate.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.
The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:
Field | Meaning |
CN | Common Name. This is commonly a hostname like www.server.com. |
O | Organization |
OU | Organizational Unit |
L | Locality |
S | State |
C | Country |
E | Email Address |
If a field value contains a comma, it must be quoted.
Encoded
char*
Default Value: ""
This is the certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.
When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.
Constructors
Certificate()
Creates a Certificate instance whose properties can be set. This is useful for use with CERTMGR when generating new certificates.
Certificate(const char* lpEncoded, int lenEncoded)
Parses Encoded as an X.509 public key.
Certificate(int iStoreType, const char* lpStore, int lenStore, const char* lpszStorePassword, const char* lpszSubject)
CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a string (binary- or Base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

IPWorksList Type
Syntax
IPWorksList<T> (declared in ipworks.h)
Remarks
IPWorksList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the FileMailer class.
Methods | |
GetCount |
This method returns the current size of the collection.
int GetCount() {}
|
SetCount |
This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection.
int SetCount() {}
|
Get |
This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified.
T* Get(int index) {}
|
Set |
This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class.
T* Set(int index, T* value) {}

IPWorksStream Type
Syntax
IPWorksStream (declared in ipworks.h)
Remarks
The FileMailer class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the IPWorksStream interface and pass the FileMailer class an instance of that concrete class.
When implementing the IPWorksStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.
Properties | |
CanRead |
Whether the stream supports reading.
bool CanRead() { return true; } |
CanSeek |
Whether the stream supports seeking.
bool CanSeek() { return true; } |
CanWrite |
Whether the stream supports writing.
bool CanWrite() { return true; } |
Length |
Gets the length of the stream, in bytes.
int64 GetLength() = 0; |
Methods | |
Close |
Closes the stream, releasing all resources currently allocated for it.
void Close() {} This method is called automatically when an IPWorksStream object is deleted. |
Flush |
Forces all data held by the stream's buffers to be written out to storage.
int Flush() { return 0; } Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0. |
Read |
Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.
int Read(void* buffer, int count) = 0; Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed. |
Seek |
Sets the current position within the stream based on a particular point of origin.
int64 Seek(int64 offset, int seekOrigin) = 0; Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:
Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported. |
Write |
Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.
int Write(const void* buffer, int count) = 0; Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed. |
Config Settings (FileMailer Class)
The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.FileMailer Config Settings
0 | 7-bit |
1 | Quoted-Printable |
2 | Base64 |
3 | 8-bit |
0 | 7-bit |

SMTP Config Settings
Bearer ya29.AHES6ZRmS-8xPbpGetC1VbABJIBRdKm-c4X7wMVGAbgxdGt5q8Ts3Q
Note: When using amXOAUTH2, User must be specified, but Password is not required.
If AllowExtensions is True, the EHLO command will be sent instead of the HELO command.
It is generally a good idea to use a MaxHeaderLength of less than 100 bytes, although different mail relays and mail servers have different requirements for header lengths.
Example:
smtp1.Send();
string rawMsg = smtp1.Config("MessageHeadersString") + smtp1.Config("TransferText");
Possible values are as follows:
- "MD5"
- "SHA1" (default)
- "SHA256"
Example:
smtp1.Send();
string rawMsg = smtp1.Config("MessageHeadersString") + smtp1.Config("TransferText");
TCPClient Config Settings
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.

Note: This value is not applicable in macOS.
Note: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

Note: This value is not applicable in Java.
By default, this configuration setting is set to False.
0 | IPv4 only |
1 | IPv6 only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this configuration setting has no effect if SSLProvider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
If set to True, the class will reuse the context if and only if the following criteria are met:
- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the class is the same.
The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found, the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.
The default value is as follows:
/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ...

Root Cert ... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
Note: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList configuration setting.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert ... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.

Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
TLS1.1 | 768 (Hex 300) (Default - Client) |
TLS1 | 192 (Hex C0) (Default - Client) |
SSL3 | 48 (Hex 30) |
SSL2 | 12 (Hex 0C) |
Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.
SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:
By default when TLS 1.3 is enabled, the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.
If set to 1 (Platform provider), please be aware of the following notes:
- The platform provider is available only on Windows 11/Windows Server 2022 and up.
- SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
- If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This configuration setting is applicable only when SSLProvider is set to Internal.
If set to True, all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.
Note: This configuration setting is applicable only when SSLProvider is set to Internal.
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

0x00000001 | Ignore time validity status of certificate. |
0x00000002 | Ignore time validity status of CTL. |
0x00000004 | Ignore non-nested certificate times. |
0x00000010 | Allow unknown certificate authority. |
0x00000020 | Ignore wrong certificate usage. |
0x00000100 | Ignore unknown certificate revocation status. |
0x00000200 | Ignore unknown CTL signer revocation status. |
0x00000400 | Ignore unknown certificate authority revocation status. |
0x00000800 | Ignore unknown root revocation status. |
0x00008000 | Allow test root certificate. |
0x00004000 | Trust test root certificate. |
0x80000000 | Ignore non-matching CN (certificate CN non-matching server name). |
This functionality is currently not available when the provider is OpenSSL.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the class fails with an error.
The format of this value is a comma-separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.
To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.
In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)

Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
