Hmm... well right now, it's not a block level mirror, it's a file level mirror -
using rsync - so that will break things right?

My thought is that even if the backup is a few minutes old (currently it's every
10 minutes on the important stuff) that a duplicate delivery is better than a
missing one. Particularly with no indication of failure...

What do I have to rename / restructure / rewrite to do a cache recovery? Then in
case of failure I can move the partially delivered messages into the surviving
mailq.

Thanks Sam,
