Hi, I would be glad if anyone can give me some clue to solve foll problem: Setup: We have 2 offices : Mumbai and Nashik and have a domain called xyz.com On xyz.com, we have setup 2 pop accounts called nashik and mumbai. All the users in respective offices have been mapped as aliases to resp pop box. In both the offices a Linux box dials to ISP and sends mails as well as downloads mails from its pop3box on the domain. Both the Linux server use sendmail and fetchmail only. Problem: When [EMAIL PROTECTED] sends a mail to [EMAIL PROTECTED] and a cc to [EMAIL PROTECTED] then both the receipents get the mail but the other Linux server creates a copy of the mail for the receipent who is not present on that local system. When that message reaches the domain server on the net, it finds that the message header has already its entry and so it bounces back to the sender saying the message has been looping. SInce the sender is not sure that if the message has been delivered or not, he gets panicky. Can you suggest anything to stop this looping?
