[Mimedefang] Sendmail + MD + SA Relaying Question

This is probably a better question for the sendmail list, however I'm sure
someone out there must have a similar setup as we have (or has wrestled
with the same problems I'm having).
I am currently running multiple servers, however due to reasons beyond my
control I've had to condense our filtering mailserver (sendmail + MD + SA)
and one of our production mailservers (qmail + vpopmail) temporarily on the
same server. I've got both qmail and sendmail running bound to a single IP
each and so far it seems to work great. There are also reasons beyond my
control which are too long to explain as to why I need to run sendmail & qmail.
We have a handful of domains (20 or so) set up with sendmail+MD as the
listed MX in DNS. These domains are also configured on other mail servers
and sendmail references the proper private MX in mailertable. The domains
are actually pointed to a couple of mailservers, so I can't just set a
smart relay for the internal. All of the domains work just fine and the
mail routes how it should --
<INCOMING MAIL> -> <SENDMAIL+MD Filter> -> <QMAIL SERVER>
However, I tried to add the main domain that the machine is a part of today
as one of the 'filtered' domains. The internal mailserver is
mail.ourdomain.com and the external is challenger.ourdomain.com. When I add
ourdomain.com to mailertable with esmtp to mail.ourdomain.com and add it to
access as a relay (I don't think it actually needs to go in access.db as an
allowed relay, but I don't think it hurts either), it doesn't work. The
logs show it as using the relay of local no matter where I add it.
I'm suspecting the problem has to do with the fact that
challenger.ourdomain.com is in the same domain as the one I'm trying to
handle mail for, however I can't seem to get it to recognize that it should
redeliver the mail via esmtp to mail.ourdomain.com.
Also, one more note about it... the internal mailserver is not listed in
DNS as a MX, that's why it's in mailertable.
Has anyone else run into this and have any tips on what I can change in
sendmail to make quit thinking that it's the local MX for the domain? I can
post my mc, etc if it helps.
Thanks,
Trevor Jorgenson
