Delete Email One Year Old

How can I clean all the emails that are one year old from all my clients.

Mails are files in /home/user/mail/domain.tld, so basicly you can search all files older than 365 years (find will be your friend) and remove them. But maybe test it first and make a copy of the files :slight_smile:.

Just to add to that, dovecot has some tools that will help you with this, but once again, test, test, test, first.

The first is the ‘doveadm expunge’ command. https://linux.die.net/man/1/doveadm-expunge
Something like this might work. (not tested!)
doveadm -v expunge -u [email protected] before 2019-11-18
If you have it working for one user, then you can run the same query over all of them … at your own risk! You can use doveadm search to get the query right first in fact.

If you want to go on deleting mails over one year old from a mailbox you can add an autoexpunge flag to it. eg, you might autoexpunge a Trash folder to remove mail older than 30 days, and an Inbox over 1 year. Dovecot documentation is your starting point for this.
