When using autoexpunge = 14 days in, for example. The trash of junk folders, does that physically remove the messages from disk or simply mark them to be removed and some other action needs to be taken?
I ask because my mail server crapped out today and I discovered a Junk folder with 490,000 messages in it, and the sa-spamd and mariadb processes died a horrible death.
Haven't had time to track down what was going on, but there were definitely messages in that junk folder from 2019 (though, of course, they may have been added within the last 14 days, I can't verify that as my solution was to remove the folder and recreate a new empty maildir).

The cron option is the safest.
Run each night something like this:
#!/bin/bash
DOVEADM="/usr/bin/doveadm";
$DOVEADM expunge -A mailbox Trash savedbefore 30d $DOVEADM expunge -A mailbox Spam savedbefore 30d

Hi But if you have more users (200K) that is a problem with that scripts

You might as we save yourself an invocation by doing
$DOVEADM expunge -A \( mailbox Trash OR mailbox Spam \) savedbefore 30dBut if you have more users (200K) that is a problem with that scripts
Why would an access triggered expungement be more problematic vs a periodic cron job? If it creates intense I/O loads, you can do it at off-peak times and/or only do userbase subsets at any one time.

What dovecot version is this? There was a bug found recently that autoexpunge stopped expunging once it found first email in order which did not match expunge criteria anymore. It started from start of the mailbox and stopped when first recent email was found. And if the mails were not in order it did leave rest of the folder untouched.

dovecot-2.3.11.3 I think, I don't remember an update within the last few days.
I keep dovecot up-to-date.
