I hadn't tried using sendmail test mode ( and at first wasn't sure to how to get out of it either ;) When I'm on recipientdomain.com, and invoke sendmail with the -bt switch it finds the mx for senderdomain.com almost instantaneously. I can also /parse [EMAIL PROTECTED] without error as well. But recipientdomain.com still returns mail from the other vs with the message 451 4.1.8 Domain of sender address [EMAIL PROTECTED] does not resolve
