And you'll also want to prepare for when a virus/worm/luser places
"from:mailer at mydomain.com" as his origin address and uses your server to
send out mail. Even if you have SMTP auth or some other method of making
sure people outside don't use you as a relay, it's better for cases like
these to add "and From:127.0.0.1" or "and From:192.168.0.x" to be sure.

And besides, you want messages not to be "touched" by MailScanner, so
why not set an additional MTA process on a different port to take care
of this?

In any case, I hope this "bulk email" you talk about is not spam. I've
started to notice local spammers and local ISP-friendly spammers are
starting to use MailScanner, "amavisd", SpamAssassin's milter, and other
antispam tools. Ironic.
