See if http://wiki.dovecot.org/PopBSMTPAndDovecot helps. It looks
relevant, at least if your server uses Dovecot and DRAC.

For your setup and timelines, probably.
For the network as a whole, it wouldn't, sorry.

It's an opportunity to migrate setups that
should have been switched long ago.

Running qmail is a bad idea for reasons laid out in that document.

SMTP-after-POP (POP-before-SMTP) is a bad idea for reasons given earlier
in this thread.

I can't really judge either, I'm running Antivir on my personal host and
Sophos on a client's server -- either with amavisd-new.

As far as I can see, the DRAC integration changed in beta4; the Wiki
link at the very beginning has information that looks relevant to your problem.

Which was my case for suggesting a migration.
