Using an IMAP email account there is an option to delete "Deleted Messages" : "Remove after one week". I want to do the same with Sent Mail since I CC: all sent-mail to my inbox and it is stored on my main computer.
But I can't find a setting in iOS to auto delete Sent Mail after a certain time (but it exist on OSX). Is it okay to set my "Sent Mailbox" to the same "Trash" folder as my "Deleted Mailbox" in the "Mail Behaviors"? Will all mail then be deleted after a week? Or what is the right way to handle this?
