Build a second server with qmail. On the second server, instead of
listing your domain(s) in 'locals' and 'rcpthosts', list your domain in
'smtproutes' and 'rcpthosts'. 'smtproutes' is described in 'man
qmail-remote'.
Create an MX entry for both your main and your secondary server, and
make sure that the secondary server has a higher MX value (i.e, main is MX
5, secondary is MX 10).
If main is down, mail will queue up on the secondary. If main is
down for more than 7 days, tweak your 'queuelifetime' so that it won't
bounce. When the main server comes back up, send qmail-send a SIGALRM to
tell it to clear out the queue.
