Although you already got a lot of replys over the week-end, here is
my suggestion:

- SMTP you do with exim (any other reason why you're on this list ;-))
- use cyrus-imapd for IMAP and POP; then you can setup your users
with a sasldb, no unix users, no logins, just username/password.
the whole cyrus-imapd package is not a piece of cake to install
and run, but it does just what you want.
- I'm using mailman for mailing lists, but the current stable
release does not support virtual domains (last time I checked
the mailman home page at least). If you do need virtual domain
mailing lists, you might give a try to sympa, I believe it
supports virtual domains.

But, as you say, there are an awful lot of combinations to do what
you want.
