gnus and SMTP AUTH

[Hans-Christian Prytz <hcp_public@prytz.net>]

Hi, I'm trying to set gnus up to talk directly to my provider's SMTP
server. This server requires smtp auth in order to relay mail outside
the local domain, but not for local mail.

I've already tested this with MozillaThunderbird, and mail is delivered
outside (authentication is working).
In my .gnus I hvae the following:
(names and addresses change to protect the innocent :-)

(setq send-mail-function 'smtpmail-send-it)
(setq message-send-mail-function 'smtpmail-send-it)
(setq smtpmail-default-smtp-server "smtp.mail.server")

(setq smtpmail-auth-credentials '(("smtp.mail.server" "25" "myname" nil)
				  ("smtp.mail.server" "25" "myname" nil)))
(setq smtpmail-starttls-credentials '(("smtp.mail.server" "25" nil nil)))

This does not work, if I set smtpmail-debug-info and
smtpmail-debug-verb to t, I get the following trace buffer:

220 smtp.mail.server.local Microsoft ESMTP MAIL Service, Version: 5.0.2195.6713 ready at  Mon, 15 Dec 2003 10:57:15 +0100

I have also tried to use "smtp.mail.server.local" in the credentials
above, but that didn't help.
To me it seems like gnus doesn't detect that auth is availible. Could
this perhaps be caused by the "^M"'s the exchange server adds to every
line?

Any other suggestions on this subject would be great.

Thanks
