Share real email addresses between MailScanner and Exchange

If you use milter-sender, you'll need to compile libmilter in sendmail.
Milter-sender is not that hard to setup. It's much easier than LDAP

I should also note that the 10,000 messages are the dead messages I can
account fo.r.

And I am hoping that their is something I can integrate with Sendmail
without re-compiling anything.

I can have whatever it is communicate back to an exchange 2003 server or
an AD server if need be.
