The check_mail rule cleanup option previously broke due to incorrect migration when editing and saving the rule. This issue has now been fixed.

Users who experienced the cleanup option not working as expected in their check_mail rules may need to re-save or adjust these rules to ensure proper functionality and monitoring behavior.
