Please, I need help. Bear with me while I describe the problem. Let's say I have two email accounts set up, user1 and user2. Each one has been set up for quite some time and both have worked as expected for years. If I send an email from user1 a copy of the message drops in the sent folder of user1 and the reply comes back to user1, and if I send an email from user2 a copy of the message drops in the sent folder of user2 and the reply comes back to user2. Not any longer. Now, if I send an email from user1, a copy of the message drops in the sent folder of user1 and the copy clearly says it was sent from user1's email. However, the reply comes back to user2's email inbox. The source of the message clearly shows it was sent TO: user2, Delivered-To: user2, Received: from line says it is for <user2>. This has been going on since the latter part of last year.
