Hmm...A read only mailbox maybe.
I know...a single mail that can be downloaded once by every user which says a 
server status until system is fully online, could even be held in the config 
file.  A small DB in RAM or a file or something could state who has 'deleted' 
the message so they don't download it twice.
Either that or give them a BOFH excuse when they phone :)
The phones went non-stop for 4 hours when our NFS failed, everyone but me was 
at a trade show, and due to a bug in exchange a customer of a customer had 
accidentally generated several million E-Mails over 24 hours with the bounces 
pointed at us which filled the backup NFS server HDD so that wasn't reliable.  
It would have been so much easier if I could have switched the phones off :)
I had a fun day :)

Andrew
