I have an account at Pipeline (one of the two original consumer online companies from the late 80's/early 90's now owned by Earthlink). On my Android phone, when I delete an email from the inbox on my Mac or my iPad, it is automatically deleted from the phone. I would like the Mac and the iPad to automatically trash an email that I delete on any of my two Apple devices or my phone to delete on all of the devices. Similarly, if I send from the phone I would like it to sync. The Pipeline account is, in fact, a POP3 account. I hear what you are saying but I can't figure out how Android is able to do it and the Apple devices don't.
