MX records with short TTL on the MX host A records (1 hour) that would be changed in an emergency would only get the mail sent to another ip address. At that ip address, if you wanted access to mailboxes there, you'd have to duplicate the Imail registry on that box. Doing that is made more difficult if you have frequently changing mail domains and/or accounts. >3) What about the mailboxes on box 1 if it crashes? Are they gone? yes. > 4) Do I need to maintain duplicate user accounts on both boxes? yes, if you want access to mailboxes during the period of unreachability of the main mailbox. >5) If box 1 goes down for a bit... and I switch to box 2.... then get box 1 >back up and running. Can I get email that is sitting on box 2 over to box >1? Easily? :-) not really, some mail will inevitably be left on the backup server, esp if you have webmail users who like to leave mail on the servers. getting those mailboxes copied back to the primary server which now has old+new mail is not trivial >I'm sure someone in the group has/is dealing with this and can provide some >great insight to all of us! it's a FAQ.
