Subject: bug#26307: 25.1; smtpmail hard-coded auth mechanism order does not allow coping with misbehaving servers
Date: Thu, 30 Mar 2017 08:54:33 +0200 [thread overview]
Message-ID: <8737dvdzkm.fsf@poste.it> (raw)
In GNU Emacs 25.1.1 (x86_64-slackware-linux-gnu, GTK+ Version 2.24.30)
the library "smtpmail.el" contains the hard-coded list of authentication
mechanisms to try in sequence:
(defconst smtpmail-auth-supported '(cram-md5 plain login)
"List of supported SMTP AUTH mechanisms.
The list is in preference order.")
it would be useful to have a public API mechanism to change such order
in case the server misbehaves when using the cram-m5 method.
I am customer of a mail service using a server that advertises to
support the cram-md5, plain and login methods but then when trying
cram-md5 the authentication fails; the login method succeeds.
Just changing the above code to:
(defconst smtpmail-auth-supported '(login cram-md5 plain)
and recompiling fixes my problems.
It is hard to contact the service administrators and having them fix
the problem, so a workaround is useful.
TIA
