I agree that that is a waste of time to do it more than once, I only
do it on boot-up to get the queued mail pushed quickly then leave the
backup MX to deliver after that (I often don't want to wait for
~30minutes until my email appears).   The backup  should deliver
immediately when the primary is up not to mention that other delivery
agents should direct deliver to the primary when it is reachable (note
that I leave out spammers tactics to deliberately deliver to
secondaries as the anti-spam/AV measures are usually less there).

Thanks
Mark
