I can see a few problems with that idea: 1) I would be unable to reject unknown users with the backup MX, so there would be a huge backlog of DSNs generated when the main MX comes back online. Currently 80% of the incoming connections are rejected for unknown users. 2) I'm not sure I can build and configure everything in an acceptable downtime window. 3) A ton of customers breathing down my neck and demanding their email NOW! :) My preferred method is to get a brand new box, configure everything on it from scratch, and then migrate everything, mailboxes and all, over to the new box. Then I can take the old box and rebuild it for another use. And since we're going to need a new backup server soon anyway... -- Bowie ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
