You can do this with Cyrus IMAPd authenticating against an LDAP
directory, RDBMS, flatfile, etc via SASL.

I currently authenticate against LDAP via PAM, but it should only
involve changing one config file to go direct to LDAP instead.

I'm not using virtual domains, but Cyrus definitely supports them and
virtual users. That's pretty much what it's designed for. The downside
is that it can be a little ... interesting to configure.

Postfix and Cyrus IMAPd should do it nicely.
