I have the problem, that a bounce mailbox I am using ran full, and it's kind of hard to monitor , since the joblog of CiviCRM needs to be watched (Bounce Mail Cronjob).
Since Civi is managing the mailbox anyways, and moves mails to CiviMail/processed and CiviMail/ignored, shouldn't CiviCRM clean up afterwards and delete old mails? Or shouldn't there be at least an option for that?
Maybe there is an extension implementing that, but I haven't found anything yet.
