We have our main server which handles primary DNS, mail, and web traffic. I have another machine which I would ilke to take over functions in the event of primary server failure. DNS is the easy one as secondary will be queried when primary does not respond. For mail, I guess I can define another Mail eXchanger (MX Record in the DNS files) with a lower priority right? Well, if this machine receives mail, how do I have it feed the mail back to the main server when it comes back up? Also, do I need to duplicate all acounts on the backup machine to have it receive the mail without bouncing it. Also, in terms of having a backup web server, I guess I would either hack or get a special named which would hand out different IP addresses (for the backup server) in the event of primary server downtime. Any help on these topics would be greatly appreciated.
