yes, one of our backups schemes is that one. We also use Cyrus 2.3's =

unexpunge and the flashcopy feature our SAN system offers.

Correct.

So? I don't see the problem. We only offer the service to IMAP users. POP =

users are on their own. If they don't back up, too bad. So if you know the =

date, you just get all files from that date back, excepting files that are =

already there. The numbers are strictly ascending and aren't reused, so =

it's safe to just restore those that aren't already there. Worst case the =

user will have a day's worth of spam to go through. Just don't forget to =

run reconstruct ...
