This memo splits message submission from message relay, allowing
each service to operate according to its own rules (for security,
policy, etc.), and specifies what actions are to be taken by a
submission server.

Message relay and final delivery are unaffected, and continue to use SMTP
over port 25.

When conforming to this document, message submission uses the
protocol specified here, normally over port 587.

This separation of function offers a number of benefits, including
the ability to apply specific security or policy requirements.  

This is now a Draft Standard Protocol.

protocol for the Internet community,and requests discussion and 
suggestions for improvements.Please refer to the current edition of the
