I'm transitioning from Entourage to Mail, and I cannot figure out how to set a rule in Mail that tells it to check the header for mail I sent from my iPhone, mark it as read, and move it to the "sent" mail folder. Obviously, with IMAP, it's not an issue, but two of my addresses still only support POP mail, so I have to figure this out. On Entourage, I used "X-Mailer contains 'iPhone Mail,'" along with my sent from name. In Apple Mail, I tried to edit the header list to include X-Mailer, but that didn't work, and I can't think of how to make this work. It's late, I've searched, and I'd appreciate any suggestions.
