It's really very easy when you know it (as always). As I was sure about, it didn't have anything to do with my local-host-names file(s) or another place where I accidentilly had left the domain name in.
The solution was to put the following line in sendmail.cf:
O DontProbeInterfaces=True
As I said, very easy, but not if you don't know it. I hope it will become of someone someday.
Thanks a lot to everybody who replied to my thread!

Subject: Re: get local sendmail to use MX records
I'm 100% sure this is not the case and here is why. I figured something out.
All my servers do the same thing. It has something to do with the reverse DNS pointers of some domains.
For example. I have (another) server running with 20 domains under 4 ip addresses where I never ever touched sendmail or its configuration files. 4 of the domains have a reverse DNS pointer to one of the 4 ips. Sendmail handles 16 domains well (= looks up MX records and delegates the mail to the right server) and tries to handle the mail of 4 domains itself. Needles to say that those 4 domains are the ones that have reverse pointers to the 4 ips attached to that particular server.
I tested this on 5 servers and its the same everywhere.
I hope one of you knows what to do with this information. I spotted the problem now, but I don't know how to solve it. Clearly sendmail prefers a reverse pointer to a domain above looking up the MX records and using them, but how can I let it stop doing that?
Thanks!

I really don't understand it at all now.
I emptied my virtusertable and local-host-names files. I really don't know why this happens.
Did you look in your mailertable file?
You have domain.com listed in one of your sendmail config files, that is the only explanation. Or you have it in /etc/hosts. or in /etc/rc.conf. it's somewhere.
It is problems like this is why when your running commercial servers that you create build sheets for each server. That is, you record on a separate document EVERY configuration step of any significance that you or anyone else does. Sorry you had to find this out the hard way. You probably have domain.com secreted in some hack you forgot that you did. Maybe one of these days when you do a nuke and repave you will remember to start a build sheet.
