We do offer smtp/tls, imap/tls and imaps, pop3/tls and pop3s.

The way I see it, TLS and SSL work like this (analogous to PGP):
You're almost right.

Almost. The asymetric encryption is only used to negotiate a symetric
session key

Hi
SMTP/TLS does not encrypt individual messages - as it's name implies, it
works on the *transport* layer. And there, the public key exchange is
used to agree on a symmetric session key.
PGP works the same way. The data is encrypted using a random symmetric
key, then this symmetric key is

Hi Tonnerre,
From a cryptographical point of view, this would be a dangerous setup.
You're transmitting the same message encrypted (local MX - Client)
as well as unencrypted (sending MX - local MX). This leaves you
open to a known plaintext attack against your server's private key,
