Hey, that's a pretty funky idea :)

We use a nginx proxy with an authentication daemon which rejects all
login attempts as admin.  Our imap machines are firewalled so that
the only ways you can talk to them are imap or pop via the nginx proxy
or send incoming emails to our mxes which will inject them via lmtp to
the spam scanning machines which do the final delivery.

I do like the different configs for a simpler network layout in a
smaller system though.  Very clever!
