Hey all,
I have a Postfix/Squirrelmail mail server set up running as a test box right now. It will be replacing our primary mail server (running Novell) in the near future, but we wanted to do some testing and trial runs before moving everyone over to it. So, what I'm looking for a way to do is to move only some people over to it while leaving the bulk of the users on the old system. However.. I'm not sure how to do this.
Mail for our domain comes into a Virus Wall box, which scans all incoming messages for viruses and SPAM, then forwards it to an internal IP. So it would be easy enough to set up all the users on the Postfix/Squirrelmail box and have all new mail come in there. But, since I want to try just a handful of users first, I was wondering if there is a way to set just them up on the box, and have Postfix forward messages for unknown users to the other server. It kind of sounds like the luser_relay parameter might be able to do it, but since the destination domain would be the same as the mydestination parameter, I'm not sure how to set it up to forward. Can I specify an IP address to forward to somehow for unknown recipients that all messages would be sent to?
Thanks for taking the time to read all this... please just ask if any additional information is needed.
