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

Syntax

TipgPHTMLMailer

Remarks

The PHTMLMailer component 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 specify a recipient key using the RecipientKey* properties. For instance: PHTMLMailer1.RecipientKeyCount = 1 PHTMLMailer1.RecipientKeyKeyring(0) = "c:\my_keyring_dir" PHTMLMailer1.RecipientKeyUserId(0) = "recipient@nsoftware.com" The specified public key will be used to encrypt the message when Encrypt is called.

Sign

To sign a message specify a recipient key using the Key* properties. For instance: PHTMLMailer1.KeyCount = 1 PHTMLMailer1.KeyKeyring(0) = "c:\my_keyring_dir" PHTMLMailer1.KeyUserId(0) = "sender@nsoftware.com" PHTMLMailer1.KeyPassphrase(0) = "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 the Key* properties and encrypted with the public keys defined in the RecipientKeys* properties.

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).

AuthMechanism Property (PHTMLMailer Component)

This property is used when connecting to the mail server.

Syntax

__property TipgPHTMLMailerAuthMechanisms AuthMechanism = { read=FAuthMechanism, write=FSetAuthMechanism };

enum TipgPHTMLMailerAuthMechanisms {
  amUserPassword=0,
  amCRAMMD5=1,
  amNTLM=2,
  amAPOP=3,
  amSASLPlain=4,
  amSASLDigestMD5=5,
  amKerberos=6,
  amXOAUTH2=7
};

Default Value

amUserPassword

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 (PHTMLMailer Component)

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

Syntax

__property String BCc = { read=FBCc, write=FSetBCc };

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 component 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 (PHTMLMailer Component)

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

Syntax

__property String Cc = { read=FCc, write=FSetCc };

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 component 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.

Remarks

The user Id of the key. When a key is loaded this property is populated with the user Id associated with the key. This property may be set to load a key from the Keyring. When this property is set the component will search the Keyring for a key associated with the UserId specified.

When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and KeyOtherUserIds after loading the key.

The UserId format is:

FirstName LastName (Comment) <Email>

When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The component will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP component's RecipientInfo event.

LocalHost Property (PHTMLMailer Component)

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

Syntax

__property String LocalHost = { read=FLocalHost, write=FSetLocalHost };

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 component initiate connections (or accept in the case of server components) only through that interface.

If the component 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.

Data Type

String

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.

Data Type

Integer

MailServer Property (PHTMLMailer Component)

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

Syntax

__property String MailServer = { read=FMailServer, write=FSetMailServer };

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 component 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 component 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 (PHTMLMailer Component)

Date of the mail message (optional).

Syntax

__property String MessageDate = { read=FMessageDate, write=FSetMessageDate };

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 component

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.

When this property is set, the component 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>";

Data Type

String

MessageId Property (PHTMLMailer Component)

The Message Identifier for the message.

Syntax

__property String MessageId = { read=FMessageId, write=FSetMessageId };

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.

""

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 component 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.

Data Type

String

OtherHeaders Property (PHTMLMailer Component)

An RFC 822 compliant string consisting of extra headers.

Syntax

__property String OtherHeaders = { read=FOtherHeaders, write=FSetOtherHeaders };

Default Value

""

Remarks

Timeout Property (PHTMLMailer Component)

A timeout for the component.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

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 component will wait for the operation to complete before returning control.

The component 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 component raises 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.

Data Type

Integer

component.AttachmentCount = 1; component.AttachmentName(0) = "name"; component.AttachmentFile(0) = "C:\file.txt";

Config Method (PHTMLMailer Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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 Component)

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

Syntax

void __fastcall 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()

ProcessQueue Method (PHTMLMailer Component)

Sends the messages which have previously been queued into QueueDir .

Syntax

void __fastcall 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 Component)

Queues the message into QueueDir .

Syntax

String __fastcall 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 Component)

Resets all the message headers to empty.

Syntax

void __fastcall 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 Component)

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

Syntax

void __fastcall Send();

Remarks

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

__property TipgPHTMLMailerKeyPassphraseEvent OnKeyPassphrase = { read=FOnKeyPassphrase, write=FOnKeyPassphrase };

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 KeyPassphrase property before attempting the operation.

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

• AddUserId
• SignUserId
• ChangeExpirationDate
• ChangePassphrase

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

• Decrypt

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 Component)

Shows the progress of the operation.

Syntax

typedef struct {
  String Message;
} TipgPHTMLMailerStatusEventParams;
typedef void __fastcall (__closure *TipgPHTMLMailerStatusEvent)(System::TObject* Sender, TipgPHTMLMailerStatusEventParams *e);
__property TipgPHTMLMailerStatusEvent OnStatus = { read=FOnStatus, write=FOnStatus };

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 Component)

Fired while the message text gets transferred to MailServer .

Syntax

typedef struct {
  int Direction;
  __int64 BytesTransferred;
  int PercentDone;
  String Text;
  DynamicArray<Byte> TextB;
} TipgPHTMLMailerTransferEventParams;
typedef void __fastcall (__closure *TipgPHTMLMailerTransferEvent)(System::TObject* Sender, TipgPHTMLMailerTransferEventParams *e);
__property TipgPHTMLMailerTransferEvent OnTransfer = { read=FOnTransfer, write=FOnTransfer };

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.
