What Jeremy didn't tell you is that the passwd.$domain and shadow.$domain are
the difficult part. I have a patch against the exim source trees (>3.22) to
provide a separate lookup, which implements searching in a directory.

Thus:

local_domains = yadda : yadda : dirsearch;/virtual/mail/aliases

and then a

domain_aliases:
driver=aliasfile
[...]
file=/virtual/mail/aliases/$domain

see http://colondot.net/sw/dirsearch.shtml

I use cyrus imapd, but as long as the IMAP subsystem is separate and
handles it's own management, anything is possible :-)

In terms of the virtual domain stuff, however, this howto document is
extremely broken, at some point I'll have to get round to writing the
document about how I've done it, which is subtly different, in that the
front facing addresses that redirect to internal addresses, which don't
resolve from outside, but which force mailman delivery.

You will probably want that patch so you can just drop local domain
handlers in...
