I recently decided to rid my inbox in Mail of old messages. I created a rule to move them 5+ dats after being sent or received by me to Archive. This had precisely no effect, so I manually selected the messages that I wanted toclear from my Inbox, and moved them to Archive. By the time that I had reached the stage of deciding that I should be obliged to move the messages manually, I must have tinkered with the settings in Mail. At all, I now have messages in AllMail that ouoght to be in Inbox, messages that I have read are not marked as read, there seem to be multiple copies of messages, and, when I try to delete or move them, I do not achieve the result. I use GMail.
