Thats a great and informative breakdown. I guess I just don't see a
benefit of using either over another.
It would appear that using SSL where the session is assumed before
established to be encrypted rather
than switching to encrypted just saves time. They both appear to do
the same thing. Obviously from what
I read, TLS is newer than SSL but sometimes thats not always a good
thing. I just don't know in this case.
Do you recommend I do one over the other? I don't really have a
requirement here at all yet so that being
said, I would rather someone who has better understand of this tell me
what they would do for a simple
Postfix / Dovecot install on a Linux server.
