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?
