PHTMLMailer Class

Properties   Methods   Events   Config Settings   Errors  

The PHTMLMailer class is used to send encrypted and/or signed HTML-formatted emails with or without any attachments using OpenPGP.

Syntax

ipworksopenpgp.Phtmlmailer

Remarks

The PHTMLMailer class offers an easy-to-use interface that supports decrypting and verifying signatures of encrypted and signed emails using OpenPGP. It enables you to create messages bound for multiple recipients with different keys, simultaneously encrypt and compress with the most popular compression algorithms, and control other aspects such as the encrypting algorithm to use.

Construct the Message

To begin specify common email properties such as SendTo, Cc, BCc, Subject, and MessageText. Connection information is specified by setting MailServer and MailPort.

Encrypt

To encrypt a message add the recipient's public key to RecipientKeys. For instance: phtmlmailer.RecipientKeys.Add(new Key("c:\\my_keyring_dir", "recipient@nsoftware.com")); The specified public key will be used to encrypt the message when Encrypt is called.

Sign

To sign a message add the sender's private key to Keys. For instance: phtmlmailer.Keys.Add(new Key("c:\\my_keyring_dir", "sender@nsoftware.com")); phtmlmailer.Keys[0].Passphrase = "password"; The specified private key will be used to sign the message when Sign is called.

Sign and Encrypt

To both sign and encrypt a message call SignAndEncrypt. The message will be signed with the private keys specified in Keys and encrypted with the public keys specified in RecipientKeys.

Add Attachments

To add attachments simply call AddAttachment. The ProcessAttachments setting specifies whether attachments are also encrypted and signed.

Send

Once all the appropriate properties have been set call the Send method and the message will be sent to its intended recipient(s).

Attachments Property (PHTMLMailer Class)

This property contains paths of the files to attach to the message.

Syntax

public FileAttachmentList getAttachments();


public void setAttachments(FileAttachmentList attachments);

Remarks

This property contains the path of a file on your system to be sent as an attachment with your message. The class will open the file and encode its contents in MIME format.

Example 1: Adding an Attachment

component.AddAttachment("C:\file1.zip"); component.AddAttachment("C:\file2.zip"); component.Send(); Example 2: Using an Attachments Collection

component.Attachments.Add(new nsoftware.IPWorks.FileAttachment("name", "C:\file.txt"));

This collection is indexed from 0 to size -1.

This property is not available at design time.

AuthMechanism Property (PHTMLMailer Class)

This property is used when connecting to the mail server.

Syntax

public int getAuthMechanism();


public void setAuthMechanism(int authMechanism);


Enumerated values:
  public final static int amUserPassword = 0;
  public final static int amCRAMMD5 = 1;
  public final static int amNTLM = 2;
  public final static int amAPOP = 3;
  public final static int amSASLPlain = 4;
  public final static int amSASLDigestMD5 = 5;
  public final static int amKerberos = 6;
  public final static int amXOAUTH2 = 7;

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.

BCc Property (PHTMLMailer Class)

This property includes a comma-separated list of addresses for blind carbon copies (optional).

Syntax

public String getBCc();


public void setBCc(String BCc);

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 collection before setting this property to remove previous recipients.

Cc Property (PHTMLMailer Class)

This property includes a comma-separated list of addresses for carbon copies (optional).

Syntax

public String getCc();


public void setCc(String cc);

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 collection before setting this property to remove previous recipients.

Command Property (PHTMLMailer Class)

This property is used to send additional commands directly to the server.

Syntax

public void setCommand(String command);

Default Value

""

This property is not available at design time.

LastReply Property (PHTMLMailer Class)

The last reply from the server.

Syntax

public String 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 can also be retrieved through the PITrail event.

This property is read-only.

LocalHost Property (PHTMLMailer Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

public String getLocalHost();


public void setLocalHost(String localHost);

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 multi-homed 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 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 multi-homed 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.

MailPort Property (PHTMLMailer Class)

The server port for SMTP (default 25).

Syntax

public int getMailPort();


public void setMailPort(int mailPort);

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 implicit SSL, use port 465 (please refer to the SSLStartMode property for more information).

This property is not available at design time.

MailServer Property (PHTMLMailer Class)

The name or address of a mail server (mail relay).

Syntax

public String getMailServer();


public void setMailServer(String mailServer);

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 (a UNIX host for example), 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 and 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.

MessageDate Property (PHTMLMailer Class)

Date of the mail message (optional).

Syntax

public String getMessageDate();


public void setMessageDate(String messageDate);

Default Value

"*"

Remarks

If this property contains a non-empty 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.

MessageHTML Property (PHTMLMailer Class)

This property includes the HTML version of the message.

Syntax

public String getMessageHTML();


public void setMessageHTML(String messageHTML);

Default Value

""

Remarks

This property contains the HTML version of the message.

When this property is set, the class automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.

Example. Setting MessageHTML:

component.MessageHTML = "<b>Hello</b>, my name is <i>Tom</i>";

MessageId Property (PHTMLMailer Class)

The Message Identifier for the message.

Syntax

public String getMessageId();


public void setMessageId(String messageId);

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.

MessageRecipients Property (PHTMLMailer Class)

The collection of recipients of the message.

Syntax

public MessageRecipientList getMessageRecipients();


public void setMessageRecipients(MessageRecipientList messageRecipients);

Remarks

This collection is indexed from 0 to size -1.

MessageText Property (PHTMLMailer Class)

This property includes the plaintext version of the message.

Syntax

public String getMessageText();


public void setMessageText(String messageText);

Default Value

""

Remarks

This property is a plaintext version of the HTML message. This is necessary for recipients with legacy mail readers that do not support HTML.

The MessageHTML property contains the HTML version of the message. When MessageHTML is set, the class automatically computes a plaintext version of the text and puts it into this property. You may choose to override this default text with your own version.

OtherHeaders Property (PHTMLMailer Class)

An RFC 822 compliant string consisting of extra headers.

Syntax

public String getOtherHeaders();


public void setOtherHeaders(String otherHeaders);

Default Value

""

Remarks

This property contains a string of headers to be appended to the message headers created from other properties like SendTo, Subject, etc.

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 (Send an Email With 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();

A mail address to which to reply (optional).

Syntax

public String getReplyTo();


public void setReplyTo(String replyTo);

Default Value

""

Remarks

If this property contains a non-empty string, a Reply-To SMTP header is created for the message. This header shows the address to use for replies (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.

SendTo Property (PHTMLMailer Class)

A comma separated list of addresses for destinations (required).

Syntax

public String getSendTo();


public void setSendTo(String sendTo);

Default Value

Examples of valid addresses are: "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 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 collection before setting this property to remove previous recipients.

Sensitivity Property (PHTMLMailer Class)

Sensitivity of the mail message (optional).

Syntax

public int getSensitivity();


public void setSensitivity(int sensitivity);

Syntax

public Certificate getSSLAcceptServerCert();


public void setSSLAcceptServerCert(Certificate SSLAcceptServerCert);

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.

Please note that this functionality is provided only for cases where 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.

SSLCert Property (PHTMLMailer Class)

The certificate to be used during SSL negotiation.

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:

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 the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

SSLServerCert Property (PHTMLMailer Class)

The server certificate for the last established connection.

Syntax

public Certificate getSSLServerCert();

Remarks

SSLServerCert contains the server certificate for the last established connection.

The subject of the mail message (optional).

Syntax

public String getSubject();


public void setSubject(String subject);

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.

Timeout Property (PHTMLMailer Class)

A timeout for the class.

Syntax

public int getTimeout();


public void setTimeout(int timeout);

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 throws an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. 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.

User Property (PHTMLMailer Class)

A user identifier to login as in the MailServer .

Syntax

public String getUser();


public void setUser(String user);

This property is not available at design time.

AddAttachment Method (Phtmlmailer Class)

This adds FileName as an attachment.

Syntax

public void addAttachment(String fileName);

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 2: Using an Attachments Collection

component.Attachments.Add(new nsoftware.IPWorks.FileAttachment("name", "C:\file.txt"));

Config Method (Phtmlmailer Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

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.

Connect Method (Phtmlmailer Class)

This method connects to the mail relay and sends the SMTP HELO command.

Syntax

public void connect();

Remarks

This method connects to the mail relay and sends the SMTP HELO command, thus preparing to send messages. Any number of messages can later be sent using the Send method.

Example. Connecting and Sending an Email:

control.MailServer = "MyServer" control.From = "me@server.com" control.SendTo = "recipient@server.com" control.Subject = "My Subject" control.MessageText = "This is the message body" control.Connect() control.Send() control.Disconnect()

Disconnect Method (Phtmlmailer Class)

This method disconnects from the SMTP server.

Syntax

public void disconnect();

Remarks

This method disconnects from the mail relay.

DoEvents Method (Phtmlmailer Class)

Processes events from the internal message queue.

Syntax

public void 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.

Encrypt Method (Phtmlmailer Class)

Encrypts the message.

Syntax

public void encrypt();

Remarks

This method encrypts the specified message.

The message is encrypted with the public keys specified in RecipientKeys.

When encrypting, the following properties may be used to further configure the class:

• CompressionMethod
• EncryptingAlgorithm

Interrupt Method (Phtmlmailer Class)

Interrupt the current method.

Syntax

public void interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ProcessQueue Method (Phtmlmailer Class)

Sends the messages which have previously been queued into QueueDir .

Syntax

public void processQueue(String queueDir);

Remarks

This method sends the messages which have previously been queued into QueueDir. The PITrail event shows the interaction with the server as messages as are processed.

This method looks in the directory for files with 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.

Queue Method (Phtmlmailer Class)

Queues the message into QueueDir .

Syntax

public String queue(String queueDir);

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.

The 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.

ResetHeaders Method (Phtmlmailer Class)

Resets all the message headers to empty.

Syntax

public void resetHeaders();

Remarks

This method resets all the message headers to "" (empty string). Use this method before creating a new message, so that headers from the previous message are not carried over to the next one.

Send Method (Phtmlmailer Class)

This method sends the current message and MIME-encoded attachment.

Syntax

public void send();

Remarks

This method sends the current message and 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.

Example. Send an HTML Email:

HTMLMailerControl.MailServer = "myserver" HTMLMailerControl.SendTo = "recipient@myserver.com" HTMLMailerControl.From = "me@myserver.com" HTMLMailerControl.Subject = "My Subject" HTMLMailerControl.MessageHTML = "<b>Hello</b>, my name is <i>Tom</i>" HTMLMailerControl.Send

SetMessageHTMLStream Method (Phtmlmailer Class)

This method sets the stream from which the class will read the HTML version of the message.

Syntax

public void setMessageHTMLStream(java.io.InputStream messageStream);

Remarks

This method sets the stream from which the class will read the HTML version of the message. Once set, the class reads the content of the stream and populates the MessageHTML property with the HTML version of the message. The corresponding plaintext version is provided in the MessageText property.

When this property is called, the class automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.

Sign Method (Phtmlmailer Class)

Signs the message.

Syntax

public void sign();

Remarks

This method signs the specified message.

The message is signed with the private key specified in Keys.

When signing, the following properties may be used to further configure the class:

• ClearSignature
• SigningAlgorithm

SignAndEncrypt Method (Phtmlmailer Class)

Signs and encrypts the current message.

Syntax

public void signAndEncrypt();

Remarks

This method signs and encrypts the specified message.

The message is encrypted with the public keys specified in RecipientKeys and signed with the private key specified in Keys.

When encrypting, the following properties may be used to further configure the class:

• CompressionMethod
• EncryptingAlgorithm

When signing, the following properties may be used to further configure the class:

• ClearSignature
• SigningAlgorithm

ConnectionStatus Event (Phtmlmailer Class)

This event is fired to indicate changes in the connection state.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void connectionStatus(PhtmlmailerConnectionStatusEvent e) {}
  ...
}

public class PhtmlmailerConnectionStatusEvent {
  public String connectionEvent;
  public int statusCode;
  public String description;
}

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:

EndTransfer Event (Phtmlmailer Class)

This event is fired when the message text completes transferring.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void endTransfer(PhtmlmailerEndTransferEvent e) {}
  ...
}

public class PhtmlmailerEndTransferEvent {
  public int direction;
}

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 (Phtmlmailer Class)

Information about errors during data delivery.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void error(PhtmlmailerErrorEvent e) {}
  ...
}

public class PhtmlmailerErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

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.

KeyPassphrase Event (Phtmlmailer Class)

Fired if the passphrase of current key is incorrect or empty.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void keyPassphrase(PhtmlmailerKeyPassphraseEvent e) {}
  ...
}

public class PhtmlmailerKeyPassphraseEvent {
  public String userId;
  public String keyId;
  public String passphrase;
}

Remarks

This event fires when the passphrase for the key is required. The passphrase must be specified before operations requiring the secret key are attempted. The passphrase may be supplied by setting the Passphrase parameter in this event, or by specifying the Passphrase field before attempting the operation.

The passphrase is required when using the following methods in KeyMgr:

• AddUserId
• SignUserId
• ChangeExpirationDate
• ChangePassphrase

When using the OpenPGP class, or an email-based class, the following methods require a passphrase for the key:

• Decrypt
• Sign
• SignAndEncrypt

PITrail Event (Phtmlmailer Class)

Traces the commands sent to the mail server, and the respective replies.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void PITrail(PhtmlmailerPITrailEvent e) {}
  ...
}

public class PhtmlmailerPITrailEvent {
  public int direction;
  public String message;
}

Remarks

The PITrail event is useful for debugging purposes. It shows all 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:

Progress Event (Phtmlmailer Class)

Fired as progress is made.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void progress(PhtmlmailerProgressEvent e) {}
  ...
}

public class PhtmlmailerProgressEvent {
  public long bytesProcessed;
  public int percentProcessed;
}

Remarks

This event is fired automatically as data is processed by the class.

The PercentProcessed parameter indicates the current status of the operation.

The BytesProcessed parameter holds the total number of bytes processed so far.

SSLServerAuthentication Event (Phtmlmailer Class)

Fired after the server presents its certificate to the client.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void SSLServerAuthentication(PhtmlmailerSSLServerAuthenticationEvent e) {}
  ...
}

public class PhtmlmailerSSLServerAuthenticationEvent {
  public byte[] certEncoded;
  public String certSubject;
  public String certIssuer;
  public String status;
  public boolean accept;
}

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 (Phtmlmailer Class)

Shows the progress of the secure connection.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void SSLStatus(PhtmlmailerSSLStatusEvent e) {}

}

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (Phtmlmailer Class)

Fired when the message text starts transferring.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void startTransfer(PhtmlmailerStartTransferEvent e) {}
  ...
}

public class PhtmlmailerStartTransferEvent {
  public int direction;
}

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.

Status Event (Phtmlmailer Class)

Shows the progress of the operation.

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void status(PhtmlmailerStatusEvent e) {}
  ...
}

public class PhtmlmailerStatusEvent {
  public String message;
}

Remarks

The event is fired for informational and logging purposes only. It may be used to track the progress of an operation.

The level of detail is controlled by the LogLevel setting.

Transfer Event (Phtmlmailer Class)

Fired while the message text gets transferred to MailServer .

Syntax

public class DefaultPhtmlmailerEventListener implements PhtmlmailerEventListener {
  ...
  public void transfer(PhtmlmailerTransferEvent e) {}
  ...
}

public class PhtmlmailerTransferEvent {
  public int direction;
  public long bytesTransferred;
  public int percentDone;
  public byte[] text;
}

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 and/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.

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Constructors

public Certificate();

Creates a Certificate instance whose properties can be set. This is useful for use with CERTMGR when generating new certificates.

public Certificate( certificateFile);

Opens CertificateFile and reads out the contents as an X509 public key.

public Certificate( certificateData);

Parses CertificateData as an X509 public key.

public Certificate( certStoreType,  store,  storePassword,  subject);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate( certStoreType,  store,  storePassword,  subject,  configurationString);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CyrptoAPI option. The default value is True (the key is persisted). "Thumbprint" - a MD5, SHA1, or SHA256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to cstUser, cstMachine, cstPublicKeyFile, and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate( certStoreType,  store,  storePassword,  encoded);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store.
