I'm not familiar with how LDAP works, so I would never have thought of
that. Sounds like a great idea! I do have a couple of questions from
looking at your routers config, though:

What are the CN and DC values supposed to be? Is CN the organizational
unit under which my users exist in Active Directory? And is DC the name
of my Active Directory domain? Mine ends in .local, so would it be
"DC=<my AD domain>,DC=local"?

This has nothing to do with local_domains earlier in the Exim configure
file, right? Just has to do with Exchange?

I'm not following that last part. Could you give me an example of the
contents of that file?

That would be a good thing, definitely.

Hmmm... my Exchange server is actually set up to deliver mail directly,
rather than relaying it back through the FreeBSD box. Is there an
advantage to configuring Exchange to use the FreeBSD box as a Smart Host
and relay mail through it?
Thanks for your help!
