You are missing the point. It has nothing to do with your hostname, but the sender address you are using. Sendmail can send e-mail with any sender address you'd like. You should be using a valid sender address. Also, you are also losing mail. Mail servers bounce mail back to the envelope sender. This mail disappears. > I'm just a little annoyed at people who insist of having the sending machine > call itself a valid hostname, just to cut down on spam. NOOOO, not the hostname, the envelope sender address. They are different. You are missing the point. This problem is completely solvable, with what you have now. You just need to make a config change to your mail system. Tom
