It is, of course, possible to relay based on SMTP AUTH via an MTA
running as an MSA (message *submission* agent) on port 587, as detailed
in RFC 2476.
This has the advantage that your relaying is seperated from your normal
send and receive MTA. It means you can firewall the MSA how you like (so
you can have your IP database implemented through iptables), and run
much more restrictive policies.
You can still use localhost as your smarthost, so outgoing authenticated
e-mails go through the same MTA.
