SSMTP Component [IP*Works! S/MIME V8]

Properties Methods Events Configuration Settings

The SSMTP component is used to send Internet mail using the SMTP protocol (the Internet mail standard).

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The SSMTP component is the S/MIME enabled equivalent of the IP*Works! SMTP component. In addition to standard SMTP functions the SSMTP component can sign and/or encrypt messages in a PKCS envelope. The methods and properties for encrypting and signing are identical to those provided with the S/MIME component. After setting the certificate properties, and specifying MessageText, call the Encrypt, Sign or SignAndEncrypt method before sending and the result will be stored in MessageText.

The SSMTP component implements a standard SMTP client as specified in RFC 821. It has a simple plug-and-play interface. It contains a number of properties like SendTo, Subject, From, Cc, BCc, etc. that map directly to the internet mail message headers with the same name (RFC 822). The message text is set in MessageText and/or AttachedFile. Messages are sent by calling the Send method.

The component supports message delivery to multiple recipients through the SendTo, Cc, and BCc properties. Simply specify the destination email addresses separated by commas.

The interface of the component is open-ended. New features, including MIME attachments can be supported by using the OtherHeaders property.

A number of events provide feedback during the operation of the component. The Transfer event is fired during message delivery to show the number of bytes delivered. The PITrail event traces the commands that are sent to the server and the respective replies.
