465 and 995 are for outgoing and incoming
respectively. If you use both, with SSL, I don't
know of any more secure option, other than maybe
using secure password authentication.

Secure against what? E-Mail is insecure. Authenticating yourself
when reading/writing mail is all very well but doesn't prevent anyone
either impersonating you or intercepting your mail on its way to you
or from you.

however using ssh does make man in the middle attacks harder.

But unless you're using a text mode client such as mutt (which I do by
the way) then ssh doesn't come into it. You don't use ssh with
thunderbird, eudora or any of the GUI clients. (OK, you *could* be
using 'ssh -X' to run a GUI remotely but that's usually too slow to be
practical).

I meant that using the secure smtp protocol ..thats the standard these
days. Fully encrypted at least to the mail relay, and possibly beyond that.

I misremebered it its SSL, not SSH - sorry.

I did wonder if that's what you meant. :-)

Still only encrypts between you and your ISP though, what happens
beyond that on the way to the E-Mail's destination is anybody's guess
and is essentially insecure - or at least you should assume it is.

The only way you can ensure some sort of privacy is to encrypt the
mail itself using PGP or similar. Otherwise, I repeat, E-Mails are
neither secure nor private, regardless of SSL or whatever between you
and your ISP.

Correct. but at least it takes one very weak link - a packet sniffer on
your own wifi - out of the possible lines of attack...
