Of course, i wouldn't mind other folders having this feature, too ;-) Reproducible: Always Steps to Reproduce: 1. Set retention policy of trash folder to "delete messages more than 10 days" 2. Delete a mail older than 10 days. Actual Results: The mail is immediatly deleted from trash. Expected Results: With the proposed retention policy "keep for  days", the mail should stay in trash for 10 days and then be deleted completely.
