The application is easy enough for syncing inbox for offline but for the life of me, I cannot figure out which settings I need in order to compose and queue offline for sending when I have wifi access. I'm using gmail imap. Everytime I try it I get the same error "coud not queue message". I have the queue folder ticked for synchronize for offline use - I think I've tried every combination of settings possible but still no luck. Any Help? Thanks
