Send emails shouldn't be too much of a problem. You can setup
something like heartbeat todo ip takeover and pretend to be the outgoing
mail server for a bit. Recieving is really difficult though. Almost
impossible because you would end up with mail spools in two different
places when the other box comes up and you would have to find a pop
client that would deal with that. Unless you have a third box which NFS
servers /var/spool/mail then you could setup both boxes as primary MX's
and allow either of them to deliver. But you need to make sure you get
locking right.
