Even then it is a manual failover (requires your intervention to fix). Even better would be to have an additional MX record of lower priority (higher number = lower priority) that would queue the mail for you in case of another outage. That server should be "out there" on the Internet. If you choose to do that, you'll need to find someone willing to do the backup MX hosting for you. It's really easy to setup the backup. Ask a friend. Oh, and setting up postfix on blacksheep as *backup* is probably not what you want... but I could be wrong. If the users/aliases don't exist on blacksheep it might reject the mail. mark On Fri, 2003-05-09 at 11:31, Drew Tomlinson wrote: > While my FBSD system that performs mail services for my home network was > down for a few days, it occurred to my that having a backup server would be > optimal.
