Since everybody was sure that the problem was with my fault and something had to be wrong with my files, I feel that I have to post the solution, that I was send to me to a member from the comp.mail.sendmail newsgroup. 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!
