SFileMailer Component

Properties   Methods   Events   Configuration Settings   Errors  

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

Syntax

ipworkssmime.Sfilemailer

Remarks

The SFileMailer Component is the S/MIME enabled equivalent of the IPWorks FileMailer component. In addition to standard SMTP functions the SFileMailer component can sign and/or encrypt messages with attachments 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, 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 Component supports both plaintext and SSL/TLS connections (RFC 2487). When connecting over 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 via the Config method.

The component sends a message (provided in MessageText) and one or more file attachments specified in the Attachments collection.

The recipients are specified by the SendTo, Cc, and BCc properties, and the message subject by the Subject property.

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

Other SMTP headers may be specified through the OtherHeaders property. Information about interaction with the server is provided via the PITrail event.
