Here's the situation: We (compusense.com) have qmail running on our firewall, and it passes mail to machine A which has the highest MX priority. Now machine A is running Exchange and has given me so much grief that machine A presently has a screwdriver embedded in the motherboard, so we're not going to use machine A anymore. We have a new Linux box, machine B, running qmail that I would like to give the highest MX priority to. Presently the mail that couldn't be delivered to machine A is being queued on the firewall machine. If I set up the new machine, change the DNS to reflect the fact I hate Microsoft and give machine B the highest MX priority, when the machine B comes on-line and I restart named, will qmail push all the mail in the queue to machine B, or will it still try to get mail to machine A. Is it easier just to give machine B the same IP that machine A had? Or will things just work with the new DNS setup. Much appreciated, jason van Zyl
