IMAP under iOS 8.4
I'm puzzled about the fact that mail accounts setup under iOS 8.4 is different on the iPhone from what it is on the iPad. Setup on the iPad duplicates setup on OS X. On the iPhone there is no provision for specifying/setting up an incoming server, and thus it's impossible to set up an IMAP account.
My providers is ATT/Yahoo. On my MacBook Air and on the iPad I have the account set up as an IMAP account. On the iPhone I can't do that. So I'm wondering: (1) is this the way it's always been? (My vague recollection is that it is not.) (2) Is there a conflict between the setups on the iPhone and that on the iPad and th MacBook?
Thanks,
iPhone 5c, iOS 8.1.1
