Just twice in over 1.5 million logins by over 14,000 users since the
beginning of October, occurring within 12 hours of each other (but
different users) at a weekend when things are supposed to be less busy...

Recreating the mbox files may be just about possible (I can retrieve the
last backup plus the mail deliveries since then, then plus try to do the
same deletes/purges as suggested in the logs) but as you say, probably
not worth it :)

Best Wishes,
Chris
