The SFileMailer Control is used to send emails with file attachments.

Syntax

SFileMailer

Remarks

The SFileMailer Control is the S/MIME-enabled equivalent of the IPWorks FileMailer control. In addition to standard SMTP functions, the SFileMailer control can sign and/or encrypt messages with attachments in a Public Key Cryptography Standards (PKCS) envelope. The methods and properties for encrypting and signing are identical to those provided with the S/MIME control. After setting the certificate properties, specifying MessageText, and attaching all files, call the Encrypt, Sign or SignAndEncrypt method before sending and the result will be stored in MessageText.

The FileMailer Control 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 control 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.

LocalHost Property (SFileMailer Control)

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

Syntax

sfilemailercontrol.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.

Data Type

String

MailPort Property (SFileMailer Control)

This property includes the server port for SMTP (default 25).

Syntax

sfilemailercontrol.MailPort[=integer]

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 (SFileMailer Control)

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

Syntax

sfilemailercontrol.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.

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 (SFileMailer Control)

This method disconnects from the SMTP server.

Syntax

sfilemailercontrol.Disconnect 

Remarks

This method disconnects from the mail relay.

DoEvents Method (SFileMailer Control)

This method processes events from the internal message queue.

Syntax

sfilemailercontrol.DoEvents 

Remarks

When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Encrypt Method (SFileMailer Control)

This method encrypts the message.

Syntax

sfilemailercontrol.Encrypt 

Remarks

This method encrypts the input message in a Public Key Cryptography Standards (PKCS)-encoded envelope with all of the recipient certificates specified in the MessageRecipients properties.

Note: The message headers, including the Sender, Recipient(s), and Subject, are not encrypted. If this is sensitive information, consider including these headers in the message body as a MIME entity, and providing other headers for the S/MIME wrapper.

Interrupt Method (SFileMailer Control)

This method interrupts the current method.

Syntax

sfilemailercontrol.Interrupt 

Remarks

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

ProcessQueue Method (SFileMailer Control)

This method sends the messages that previously have been queued into QueueDir .

Syntax

sfilemailercontrol.ProcessQueue QueueDir

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.

Queue Method (SFileMailer Control)

This method queues the message into QueueDir .

Syntax

sfilemailercontrol.Queue 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.

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.

Reset Method (SFileMailer Control)

This method will reset the control.

Syntax

sfilemailercontrol.Reset 

Remarks

This method will reset the control's properties to their default values.

ResetHeaders Method (SFileMailer Control)

This method resets all the message headers to empty.

Syntax

sfilemailercontrol.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 (SFileMailer Control)

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

Syntax

sfilemailercontrol.Send 

Remarks

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

SendCommand Method (SFileMailer Control)

This method sends the exact command directly to the server.

Syntax

sfilemailercontrol.SendCommand Command

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.

Sign Method (SFileMailer Control)

This method signs the current message.

Syntax

sfilemailercontrol.Sign 

Remarks

This method digitally signs the input data with the certificate provided. Certificates are provided by specifying the Certificate property. The IncludeCertificate property allows you to specify whether to include the certificate when signing the message.

SignAndEncrypt Method (SFileMailer Control)

This method signs and encrypts the current message.

Syntax

sfilemailercontrol.SignAndEncrypt 

Remarks

This method both signs and encrypts the input message into a single PKCS-encoded envelope.

Note: The message headers, including the Sender, Recipient(s), and Subject, are not encrypted. If this is sensitive information, consider including these headers in the message body as a MIME entity, and providing other headers for the S/MIME wrapper.

ConnectionStatus Event (SFileMailer Control)

Fired to indicate changes in the connection state.

Syntax

Sub sfilemailercontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)

Remarks

This 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 (SFileMailer Control)

This event is fired when the message text completes transferring.

Syntax

Sub sfilemailercontrol_EndTransfer(Direction As Integer)

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 (SFileMailer Control)

Fired when information is available about errors during data delivery.

Syntax

Sub sfilemailercontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control 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 (SFileMailer Control)

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

Syntax

Sub sfilemailercontrol_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:

SSLServerAuthentication Event (SFileMailer Control)

Fired after the server presents its certificate to the client.

Syntax

Sub sfilemailercontrol_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 (SFileMailer Control)

Fired when secure connection progress messages are available.

Syntax

Sub sfilemailercontrol_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 (SFileMailer Control)

This event is fired when the message text starts transferring.

Syntax

Sub sfilemailercontrol_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.

Transfer Event (SFileMailer Control)

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

Syntax

Sub sfilemailercontrol_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.
