This depends on how you want to "handle" the email. If you're only
the backup MX you *must not* put it in locals/virtualdomains (unless
of course you have some mechanism set up with e.g. serialmail that
sends the message on).
Because of the DNS latency we usually put domains, which we do backup-MX
for, also in smptroutes for two or three days.

It simply stays in the queue and is delivered once the best-MX host is
up again (with respect to qmails quadratic backoff algorithm).
