Is there any extension to the SMTP protocol which, for a client connection
to an SMTP server, would require that all messages originating from that
client specify a return address known by the server to be associated with
that client?
Why is the rfc2821.mailfrom address of particular address, rather than any of
the other identification information, such as rfc2821.helo, rfc2822.from or
rfc2822.sender?
