If you have an Emacs 24 with built-in gnutls support, then these
variables aren't used.

These variables no longer exist in Emacs 24.

Looking at the code in smtpmail.el, it looks like it should only save
the password if the login was successful.  However, I don't have access
to any SMTP servers that require login, so I can't reproduce this.

I think.
