The problem would be, that UFS (I assume that u want to use UFS on top of
gmirror) does not allow multiple RW mounts...
Maybe u would like afs/dfs or coda or mysql (i dont know if there r mail
exchangers, that can use mysql; maybe qmail?) better?
Or maybe u would like this self-made construction better:
Whenever an email comes in from the outside (so not from the other hot box), u
forward it via some specially crafted /etc/aliases file to the other hot box.
Then u would need something, that pop3-s both boxes simultaneously somehow
(maybe via a journal, that is sent to the other hot box every few seconds, and
that is shortened if the changes r acknowledged)... And after a crash the box
would be updated automatically via the mail queue (if the down time was not too
long)...
