I've a situation where some users keep very old messages (+5 years) on their mailboxes that are just a waste of space and due to safety reasons should also be deleted.
I find out that I could use
doveadm for this, however running something like:
doveadm expunge -u [email protected] mailbox INBOX savedbefore 1-Jan-2011
Doesn't have any effect. From my understanding email clients mark email for deletion before the
expunge is run on the server to actually remove them.
How can I mark them for deletion using
doveadm and then run the
doveadm command before or directly and completely delete them?
