Re: [Dbmail] Restoring emails
A separate table would be superfluous I think. I just have a cron job that runs dbmail-maintenance on a periodic basis, right now it's weekly, but I may change it to daily or hourly as more accounts get placed on the server. If you need to list the deleted messages an appropriate SELECT statement could be conceived of pretty easily.

Re: [Dbmail] Restoring emails
FWIW, running dbmail-maintenance -d and then -p on my system resulted in 0 messages being deleted. A check of my tables showed none listed with other than 0 status... That was with RC4 Postgresql. It looks like the various flags are being used, rather than the status. I think the idea of keeping old messages around is good from a user's point of view, but bad from an admin/resource point of view - how many GB of spam will be sitting on machines? I guess I'd like to see a less "admin-intensive" method of dealing with it... Maybe moving the deleted messages to a separate table, so that could be backed up or emptied as required.

Re: [Dbmail] Restoring emails
Well, it depends. Messages aren't actually deleted until you run dbmail-maintenance - twice. Let's see how it works: each message has an extra attribute called 'status'. For the moment, it can have the following values: 0 - new message 1 - message has been read 2 - message has been deleted (pop) or deleted&expunged (imap) by user 3 - message is set for deletion the change from 2 --> 3 is done by running dbmail-maintenance -d the change from 3 to actual deletion is done by running dbmail-maintenance -p So if you never run dbmail-maintance -p, all message are left on the server. Restoring them for a user is as simple as an UPDATE query on the messages.status field. (If any of you is interested: could be handy to have dbmail-maintenance leave deleted mesages for a certain amount of time. Shouldn't be that hard to implement, could require a database layout update.) If the message is deleted, you should indeed use a backup. regards roel Richard Barrington heeft op woensdag, 4 dec 2002 om 10:37 (Europe/Amsterdam) het volgende geschreven: I think so.

[Dbmail] Restoring emails
Hi Everyone, Sorry if it seems like I'm posting so much to the list. As I'm starting to go through dbmail I'm trying to find out how easy it is to restore any user's email for any given day? Is this more an SQL backup/restore question?
