A customer of us brought a bouncing mail problem today while she was trying to send an email to columbia.edu mail system. She can not send any mail to any account in columbia.edu. Every mail is bouncing back. However, I can send... I tried to send an email to [EMAIL PROTECTED] via my our sendmail server. Message again bounced back saying "Sender domain must resolve". Well, Like I said, any email going from [EMAIL PROTECTED] (mine) gets thru and successfull. Somehow, our customer whom uses the same email server as we do, can not.! Any ideas? Thank you!
