Following a previous suggestion I'd received to turn on autoexpunge (https://dovecot.org/pipermail/dovecot/2020-February/118281.html), I'm now trying to confirm whether or not it is doing what I expect it to do.

I've set the expiration to be 12 weeks (as shown below in the config) but a lot of the mailboxes have email in them that is much older.

Reading http://dovecot.2317879.n4.nabble.com/Dovecot-2-2-20-autoexpunge-td54644.html, I've tried using "doveadm search -u user mailbox INBOX savedbefore 2w" to see if it finds any email that is older than 2 weeks (just as a test) and it doesn't.

If I change "savedbefore" to be "sentbefore" then it works.

If "autoexpunge" is dependent on "savedbefore" working then what do I need to do to fix this?

Thanks.

Regards

Philip
