ssl.el won't work with ESMTPs STARTTLS command, because it expects to just
talk SSL from the beginning.  ESMTP and HTTPS tunneling thru a proxy server
expect you to start the SSL handshake partway thru the connection.

Some old patches I had floating around for Emacs to natively support SSL
would support this, but I never released them because of the #%!@#%@! NSA /
US restrictions (this was probably 5 years ago :).

Someone might be working on them - I sent them my old design outline (no
code), but will let them announce something when they are ready.
