make smtpmail.el use the new netrc.el file


From: Simon Josefsson
Subject: make smtpmail.el use the new netrc.el file
Date: Wed, 24 Apr 2002 21:28:03 +0200
User-agent: Gnus/5.090006 (Oort Gnus v0.06) Emacs/21.2 (i686-pc-linux-gnu)

This patch makes smtpmail.el take advantage of the new netrc.el stuff.

I bumped :version on the variable to "21.3".  Is this correct?  I
wasn't sure about that.

I am sending this message with SMTP authentication using ~/.authinfo,
but I also tested the old `smtpmail-auth-credentials' as well.  Not
tested by anyone but me though.  Ted, if you can/want, please test
it. (Ted, netrc.el has been added to Emacs, XEmacs and Oort Gnus now.)

2002-04-24  Simon Josefsson  <address@hidden>

        * mail/smtpmail.el (smtpmail-auth-credentials): Support netrc
        files as well.
        (smtpmail-try-auth-methods): Support netrc data.
        (netrc-parse): Autoload netrc.
