[BlueOnyx:22423] Purging old email

[Ernie]

I am trying to get rid of old emails from all the users Trash folders using the following
Dovecot command:


 doveadm expunge -A mailbox Trash savedbefore 30d


It gives this error:


 Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: No such file or directory 
 doveadm: Error: Failed to iterate through some users


I presume BlueOnyx doesn't use the auth-userdb that doveadm looks for my
default.

Can someone tell me the correct proceedure?
