Not really. You see, that internal domain doesn't really exist. It only
exists in email addresses for clients that use the Domino server. There
are no hosts on that secondary domain. For some reason the admin of the
Domino server wanted to give his users email addresses that ended in a
different domain name than our main domain. That didn't seem very
logical to me, but well, I didn't have any voice in the matter. The
Exchange server seems to recognize that any email it sees on heading for
the secondary domain should be passed on to Domino for processing.

I've only got DNS for the actual domain (since the secondary domain
doesn't really exist) but I added an MX entry in that db.domain.com file
so those MX records look like so:
mx 10 mail.domain.com.
otherdomain.com mx 10 domino.domain.com.

Is this okay, or is it completely wrong?

Nope. Still didn't work for me.

I'm rather confused at this point, so nothing is obvious to me :-)

Local domains list? Where is that at? /etc/mail/domaintable is empty,
and /etc/mail/local-host-names just has aliases for the localhost.

Does the MX record I stated above count?

My relay-domains file looks like:
.otherdomain.com RELAY

I'm starting to get the feeling maybe this isn't a Sendmail config
issue? Is it really sane to expect to relay mail to a domain that
doesn't exist like this?

Again, thanks for the help.
