So I have gmail set up to use imap and everything works perfectly on my iPhone. When I chose delete on my iPhone it works like hitting archive on gmail's site. When I hit delete in Mail.app it creates a "Deleted Messages" label in gmail and applies it to the message. I also have the option of mapping the Trash label to the trash in mail.app. What I really want is for an email to become archived when I hit delete in Mail.app like it does on my iPhone. Also, how come I can read mail on my iphone (or the website) and when I look in Mail.app it still says unread? Isn't the point of imap that my mail is synced everywhere?
