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?
