Sorry, I overlooked the obvious. The reason it was happenning to both machines was due to an MX record (that I PUT there. heh) Other than that, I guess someone's mailer/route is hosed and they can send, but not recieve packets from my partuclar chunk of the net. Thanks anyway for any help that would have been offered.
