(1) Secure at rest and (2) secure during transmission. Those solutions that can ensure protection for email messages at rest are superior. Solutions that only employ SSL or TLS will ONLY protect during transmission. Email content will be in in the clear at the end-points as well as on intermediate servers it may pass through. Totally inferior. Solutions like S/MIME provide protection for emails at rest as well as in transmission with no exposure of clear text.
