IMAP4 transport

The IMAP4 is largely a mail management system. It does not define a mechanism for sending mail but rather can receive mail in a number of forms, including SMTP. As such, the SST IMAP4 transport can receive messages from an IMAP4-compliant server and uses a nested SMTP transport to send messages. An IMAP4 URL has the following format:

scheme:/imap4/user:password@host:port

The :port field is optional and defaults to the standard IMAP4 port (143). Both user and host must be specified, and the :password field is required for local endpoints. (It is ignored for remote endpoints.) When sending a message, the remote endpoint's IMAP URL is translated into an equivalent SMTP URL by dropping the password and port. This assumes that there is an SMTP server running on the same machine as the receiver's IMAP server.

The IMAP4 and SMTP transports use the same communication messages and IMAP messages must also be 8-bit protected.
