Besides all of that. Emails are simple just textual object (which may become files or part of a file store of emails) that, if not protected, can be changed to say ANYTHING. Protecting them involves something like GPG signing, anything else and it is fully open to be completely re-written by anyone ....
Also, a mailbox on a server populated by encrypted messages (where a public-key infrastructure is used on the client side to handle the cryptography) is far less valuable to attackers. True, the headers can reveal very useful information for traffic analysis, but at least the contents remain confidential so long as the private keys remain protected.
