Share real email addresses between MailScanner and Exchange

[brichter]

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.
