Hi Ian, I think you perhaps misunderstand: even if you set up IMP you STILL would have had to setup those 1500 accounts. I also beg to differ - this is very clearly a mail client problem. As you have realized, Sendmail does not rewrite the From: address. This is because the mail client program is in charge of correctly putting the user@whateverdomain address into the outgoing mail. This is inherent to the SMTP protocol. Your blaming the failure of the user's mail client program to properly create the username@whateverdomain address on the mail client program itself. However, this is wrong, the client program is doing what it's supposed to be doing. If you give your users the ability to retrieve e-mail via POP3 and transmit it via SMTP then you give them the responsibility to make sure that the From address is correct. If they are unwilling or unable to do this (due either to their misunderstanding how the client program operates, or due to their logging in somewhere and allowing some mystical "thang" to change the From address) then clearly you have to either force them to use a mail client that they DO understand, or force them to use a mail client that they have no control over, and that you do. This is what IMP is. IMP is a mail client that runs ON THE MAILSERVER, instead of on a remote desktop, so instead of having a remote client that has unreachable settings, you have a mail client that is local to the mailserver that YOU can control. I also beg to differ with your statement: "...No-one checks account details every time they mail...." Guess what, _I_ do. I'm sure that any power users among your students do also. It's simple enough to do when using a mail client program like Eudora, which _does_ place the From address IN THE MESSAGE DURING COMPOSITION unlike Microsoft Outlook which hides it. In fact, that's another answer to your problem - because Eudora doesen't give a rat's ass about what drive your logged into.
