I have secondary DNS set up with my brother in Chicago for that very reason. That way if my server goes down his will answer DNS queries for me and my mail will get queued at phantom.byu.edu and mail.byu.edu and smtp.yahoo.com etc..

OK the only problem that I see is that my DNS server and Mail Server are on the same Machine, My configuration is weird and probably wrong. I have one DNS server with the Domain Registrar, the other Is ONsite here and it takes care of Local NAT translations. So would i have to talk with my Registrar and see if they would queue up my mail while I did maintanece? Or are there any more Ideas? If necessary i could get access to another box to act as a queue?
Quoting Andrew Jorgensen <[EMAIL PROTECTED]>:
To start with, you should have an MX entry in DNS. These entries have a priority field in them, so if you had someone willing to hold your mail for you until the primary came back up, as well as MX entries for both, with different priorities the magic will all happen automagically.
As for configuring a mail server to take mail for you if you're not there I can't say I have any expertise. I'm sure that it can be done.
Also, assuming your DNS isn't going down mail should queue up on the sending servers. I've heard of messages sitting for something like 30 days in some queues. Then when you come back up all of your mail will get dumped on you within a day or so.
So if your DNS is going to stay up you shouldn't lose any mail. Some people will get dilivery delay notices though, but that's okay.
