Which is more secure, IMAP or POP?
I realize IMAP and POP both support SSL/TLS connections, but I am concerned more about messages remaining on the server.
It seems POP would be more secure because can't you configure it not to leave messages on the server? Or does IMAP also support that?
Also, which protocol would be more amenable to being integrated with Lavabit-like services like Tutanota?
