That answer is very simple. gateway.townandcountry.org doesn't exist as far as the rest of the world goes. I tried doing an nslookup on it. Sendmail on the receiving side is rejecting the e-mail because of this (anti-spam stuff). What you need to do is either: 1. Make a valid DNS entry for townandcountry.org, or... 2. Have sendmail masquerade as townandcountry.org and re-write headers of all outgoing mail. -Chris > -----Original Message----- > From: David B.
