Hm.  It's hanging in the connect call itself to the SMTP server?  That's
rather odd.

If you eval the following

(make-network-process :name "smtpmail" :buffer (get-buffer-create "foo") :host 
"foo.bar.com" :service 465)

does it hang?

Yes, your SMTP server apparently requires STARTTLS, but the built-in
GnuTLS support isn't able to negotiate a connection -- I'm guessing
because of a buggy SMTP server certificate.  But that doesn't explain
the apparent hanging in `make-network-process' itself, which is just

Try evaluating this:

(defun gnutls-available-p () nil)

If you have gnutls-cli installed (and you apparently have since it works
in Emacs 23), that should disable the built-in GnuTLS library.  Are you
able to send mail then?
