I have GMAIL set up as an IMAP account on my iPhone 5 using IOS 7 and the built-in MAIL app. Can't seem to do it using Google's GMAIL app, either. I prefer to use the built-in MAIL app. I'd like to be able to have a copy of the emails I compose and send automatically copied to a SENT email folder. I've read through Google's documentation and still haven't a clue as to how to set this up. No way to create the folder on my iPhone, no way to auto forward sent emails to it. Any chance of a "walk-through" from one of the many experts here? Thanks!
