I am totally underwhelmed by Apple's Mail on both OSX 10.9.5 and iOS 8. I have iMac with OSX 10.9.5, iPad 3 and iPhone 5S with iOS 8. I would like to have my 27 FULL mailboxes & contents available (in a cloud) on all devices; including Sent Mail, (all) Inboxes, Drafts, etc. I have email accounts on my own 3 domains, as well as a Yahoo and two Gmail accounts. Can I get some recommendations for combo of iOS and OSX mail apps to give me full control everywhere over my emails? Thanks!
