I'm expunging mail in my crontab like this: doveadm search -u user1 mailbox INBOX.Trash savedbefore 30d doveadm search -u user2 mailbox INBOX.Trash savedbefore 30d doveadm search -u user3 mailbox INBOX.Trash savedbefore 30d ...
I'd rather do this: doveadm search -A mailbox INBOX.Trash savedbefore 30d but I'm told not to: "If the -A option is present, the command will be performed for all users. Using this option in combination with system users from userdb { driver = passwd } is not recommended, because it contains also users with a lower UID than the one configured with the first_valid_uid setting." I'm using userdb { driver = passwd-file } but I'm guessing that's the same thing. Am I understanding this correctly? - Grant
