I've got an iPhone 6, and I have a problem with the mail... I've have a single mail account with Comcast, and have it set up on the phone. I have the mail set up for manual update instead of push. When I do a manual fetch, it retrieves new mail just fine. So then I go to my computer and delete some mail from the server. Next I go back to the phone and do another manual fetch/update. The problem is, the mail I deleted from the server, does not get deleted from the phone. Is there some special setting somewhere that I would need to do so the sync would work? Thanks.
