Trying to get MailScanner v4.22-5 to forward messages

[Chris Lyon]

OK, this might be an easy answer and if you couldn't tell, this is my first
time trying to get MailScanner working. I have installed MailScanner 4.22-5
and have it running on a Redhat 9.0 installation. Sendmail is disabled and
I even did the 'dnl DAEMON...' to get it working from outside the box. I am
trying to get a domain routing to this box with MailScanner running on it
to my Exchange System. If I turn off MailScanner and turn on just Sendmail,
everything works fine. Mail from the outside goes to RH9.0 then to the
Exchange. As soon as I turn off sendmail then turn on MailScanner, the mail
just sits in the /var/spool/m.... directory.

Any ideas?

BTW, I turned off AntiVirus, and SpamAssassin too just to bring it down to
a basic level.
