I've just started using qpsmtpd to do SMTP AUTH against my vpopmail users with vchkpw, to avoid running a patched qmail-smtpd[1]. qpsmtpd has many spam-filtering plugins, and several queueing plugins, including one for qmail and one for any SMTP server (effectively as a proxy). It's fairly easy to extend too, if you know perl. I added a check module to allow our backup MX to only accept mail for a list of known accounts with an afternoon's work. Seperating your SMTP services into relay, inbound, and backup MX makes life a lot easier for enforcing mail policies, IMHO.
It's worth a look, perhaps. Howie. [1] actually, it's to avoid having to reconcile SMTP AUTH patches with chkuser, which I already use, and couldn't live without. I run qmail-smtpd with chkuser for the 'public' MX SMTP service, and qpsmtpd for my local user's relay SMTP server, with auth and SSL.
