Attempting to use frequent runs of the queue is not a good way to solve
this problem, it is non-predictable.

Better off to have sendmail sort mail destined to them into a seperate
/var/spool/mqueue.${DOMAIN}, then fire up a:

    sendmail -q -oQ/var/spool/mqueue.${DOMAIN}

This is a non-trivial thing to set up, and there are bits and pieces of
it described in the BAT book, look in the sections on fault tolerent and
holding someones mail for them until they come back on line.
