I have just moved from cyrus-imap to dovecot. In cyrus I had an automatic purge of messages marked as deleted with a cron job:

 /usr/lib/cyrus-imapd/cyr_expire -E 1 -X 7 -D 7

-E = Expire Days -X = Expunge days

What is the equivalent in doveadm?

 doveadm expunge -A DELETED BEFORE 1w

That should do about the same thing.

Is there any equivalent to expire messages marked as deleted? I can't remember why I have it as I set up Cyrus so long ago.

I also delete from deleted (INBOX.trash) anything older than a year. In Cyrus, it is run from an event in the configuration:

 trashPurge cmd="ipurge -s -X -f -d 365 user/*/Trash" at=0104

I would be happy to run it from cron, so does this work:

 doveadm expunge -A mailbox INBOX.trash SENTBEFORE 52w

You can use autoexpunge setting instead.

Except I get:

 doveadm(nobody): Error: mkdir(/nonexistent/.Maildir) failed:
 Permission denied (euid=65534(nobody) egid=65534(nogroup))

I can run it for the individual users but not -A.

You are missing last_valid_uid setting to exclude nobody.

Working now, thanks.

I do have an odd, sort of related question as I am seeing 2 different Trash locations.

Everyone in the family uses Thunderbird and K-9 mail. I moved all the mail to Debian12 with Dovecot from Cyrus using imapsync. In Cyrus the Trash folder is at the same level as the INBOX. After syncing the mail across, I gained an INBOX.trash folder as did the family account. A couple of other members account did not gain the INBOX.trash folder so I configured TB to use the original top level account. I have assumed this is a Dovecot thing, but I guess TB may have created it itself.

Which Trash folder would Dovecot normally create so I can standardise here? 15-mailboxes.conf has:

   mailbox Trash {
     special_use = \Trash
     autoexpunge = 52w
   }

(I've just added the autoexpunge) Does this mean I should resurrect /Trash and move the deleted mails back, adjusting TB and K-9 accordingly

I have just moved from cyrus-imap to dovecot. Interesting, I'm considering going the other way when Dovecot 2.4 is out and replication is lost ;-)

Only because my previous distro, ClearOS, used Cyrus. I urgently needed to replace ClearOS as there is no way to reinstall it in case of disaster, so I went with Debian 12 and they seem to prefer Dovecot. I only have a family server so am not so interested in replication, just a reliable backup and restore, in case of emergencies.
