When the expire cronjob actually finds a folder needs pruning, does it then purge the row from the database? Or could it update the row with the "new" oldest message's expiration time?

I guess I can test this for myself. I did just learn that emptying the Trash removes the row from the expires db. . .

I had misconfigured expires here, and think I fixed it, but in checking things over, I do find some "over age" files, and their users don't appear in the expires db. So I'm assuming it's because expiration worked on that folder some time ago, and no "new" messages have been delivered there since then to reset the expires db?

(Sometimes I wish there wasn't the db, and we could just have a nightly cronjob do all the work on all users' Trash, Spam, Virus folders -- where we pretty much expect to be constantly pruning, or shaving as it were ;)
