If I find a message that I want saved forever and not deleted automatically - what do I need to do to have it "protected?"    If I create a folder called "Saved" or somethign like that, and move it from the Inbox to the SAVED folder, will it stay there or will it be deleted after X days?    If it is deleted, how can I save it?  (I normally read message via an ipad (which is imap by  default.   Most messages can be deleted after 3 days, but there are some I want to keep forever - what do I do?)
