The PFileMailer control is used to send encrypted and/or signed plaintext-formatted emails, with any attachments, using OpenPGP.

Syntax

PFileMailer

Remarks

The PFileMailer control offers an easy-to-use interface: you can send an OpenPGP signed and encrypted message using the PSMTP control by calling the Encrypt, Sign, and SignAndEncrypt methods. Additionally, 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.

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.

Sign

To sign a message specify a recipient key using the Key* properties. For instance: PFileMailer1.KeyCount = 1 PFileMailer1.KeyKeyring(0) = "c:\my_keyring_dir" PFileMailer1.KeyUserId(0) = "sender@nsoftware.com" PFileMailer1.KeyPassphrase(0) = "password" The specified private key will be used to sign the message when Sign is called.

Encrypt

To encrypt a message specify a recipient key using the RecipientKey* properties. For instance: PFileMailer1.RecipientKeyCount = 1 PFileMailer1.RecipientKeyKeyring(0) = "c:\my_keyring_dir" PFileMailer1.RecipientKeyUserId(0) = "recipient@nsoftware.com" The specified public key will be used to encrypt the message when Encrypt is called.

Sign and Encrypt

To sign and encrypt a message in one step 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

Call the Send method once the necessary properties have been set for each recipient.

Syntax

pfilemailercontrol.KeyUserId(KeyIndex)[=string]

Default Value

""

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 control 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>

Note that for OpenPGP v6, a key may be created with or without a UserId, as the field is optional. If a key was created without a UserId, the key's Fingerprint can be used as it's identifier instead.

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 control 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 control's RecipientInfo event.

Syntax

pfilemailercontrol.LocalHost[=string]

Default Value

""

Remarks

This 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 control initiate connections (or accept in the case of server controls) 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 control 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.

This property is not available at design time.

Data Type

Integer

MailServer Property (PFileMailer Control)

This property includes the name or address of a mail server (mail relay).

Syntax

pfilemailercontrol.MailServer[=string]

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 control 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 control 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 (PFileMailer Control)

This property includes the date of the mail message (optional).

Syntax

pfilemailercontrol.MessageDate[=string]

Default Value

"*"

Remarks

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 control 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 control's RecipientInfo event.

The RecipientKeyIndex parameter specifies the index of the item in the array. The size of the array is controlled by the RecipientKeyCount property.

This property is not available at design time.

Data Type

String

ReplyTo Property (PFileMailer Control)

This property includes a mail address to which to reply (optional).

Syntax

pfilemailercontrol.ReplyTo[=string]

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 (PFileMailer Control)

This property includes a comma-separated list of addresses for destinations (required).

Syntax

pfilemailercontrol.SendTo[=string]

Default Value

""

Remarks

Examples of valid addresses are as follows: "Friendly Name" <address@company.com> or address@company.com

The control 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.

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

• AddUserId
• SignUserId
• ChangeExpirationDate
• ChangePassphrase

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

• Decrypt
• Sign
• SignAndEncrypt

UserId holds the user Id of the key the passphrase is required for.

The UserId format is:

FirstName LastName (Comment) <Email>

Note that for OpenPGP v6, a key may be created with or without a UserId, as the field is optional. If a key was created without a UserId, the key's Fingerprint can be used as it's identifier instead.

KeyId is the hex-encoded, 4-byte or 8-byte Id of the key the passphrase is required for. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

PITrail Event (PFileMailer Control)

This event traces the commands sent to the mail server, and the respective replies.

Syntax

Sub pfilemailercontrol_PITrail(Direction As Integer, Message As String)

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:

Progress Event (PFileMailer Control)

Fired as progress is made.

Syntax

Sub pfilemailercontrol_Progress(BytesProcessed As Long64, PercentProcessed As Integer)

Remarks

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

The PercentProcessed parameter indicates the current status of the operation.

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

SSLServerAuthentication Event (PFileMailer Control)

Fired after the server presents its certificate to the client.

Syntax

Sub pfilemailercontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

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 (PFileMailer Control)

Fired when secure connection progress messages are available.

Syntax

Sub pfilemailercontrol_SSLStatus(Message As String)

Remarks

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

StartTransfer Event (PFileMailer Control)

This event is fired when the message text starts transferring.

Syntax

Sub pfilemailercontrol_StartTransfer(Direction As Integer)

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 (PFileMailer Control)

Shows the progress of the operation.

Syntax

Sub pfilemailercontrol_Status(Message As String)

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 (PFileMailer Control)

This event is fired when the message text is transferred to MailServer .

Syntax

Sub pfilemailercontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)

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.
