@anki POP3. That's the key. I hate IMAP, because I don't want all my emails on all my devices all the time. I only ever fetch mail on my phone if I'm out & about. With POP3 all devices will fetch independently & deleting on one does not delete on any other. That way, I don't want my phone to auto-fetch emails I've already dealt with, just to have to delete them all again.
