SFileMailer Class

Properties   Methods   Events   Configuration Settings   Errors  

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

Syntax

class ipworkssmime.SFileMailer

Remarks

The SFileMailer Class is the S/MIME enabled equivalent of the IPWorks FileMailer class. In addition to standard SMTP functions the SFileMailer class 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 class. After setting the certificate properties, specifying message_text, and attaching all files, call the encrypt, sign or sign_and_encrypt method before sending and the result will be stored in message_text.

The FileMailer Class supports both plaintext and SSL/TLS connections (RFC 2487). When connecting over SSL/TLS the on_ssl_server_authentication event allows you to check the server identity and other security attributes. The on_ssl_status event provides information about the SSL handshake. Additional SSL related settings are also supported via the config method.

The class sends a message (provided in message_text) and one or more file attachments specified in the attachments properties.

The recipients are specified by the send_to, cc, and b_cc 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 other_headers property. Information about interaction with the server is provided via the on_pi_trail event.
