"unknown extension size 10000000" when sending mail

"unknown extension size 10000000" when sending mail

[Erik Østlyngen]

Hi,

I get the message (in the message buffer) "unknown extention size
10000000" each time I send a mail. This started to happen when I
changed to a new smtp server. Is this a message from the server, or is
it generated by some internal functions? I'm using pgnus-0.88 with
NtEmacs20.3.1. My .emacs has the following definitions:

(setq user-full-name "Erik Østlyngen")
(setq user-mail-address "Erik.Ostlyngen@ifbt.ntnu.no")

(setq message-default-mail-headers 
    "From: \"Erik Østlyngen\" <eriko@ifbt.ntnu.no>\n")
(setq message-default-news-headers 
    "From: \"Erik Østlyngen\" <Erik.Ostlyngen@ifbt.ntnu.no>\n")

(setq smtpmail-default-smtp-server "mail.stud.ntnu.no")
(setq smtpmail-local-domain nil)
(setq send-mail-function 'smtpmail-send-it)

(setq gnus-select-method (quote (nntp "news.ntnu.no")))
(setq gnus-secondary-select-methods '((nnml "private")))
(setq gnus-message-archive-group "archive")

(setq gnus-show-mime t)
(setq gnus-strict-mime t)

(load-library "smtpmail")

(load-library "message")
(setq message-send-mail-function 'smtpmail-send-it)

(custom-set-variables
 '(message-generate-headers-first t))
(custom-set-faces)

Yes.  The RFC-specified SMTP extensions for provision of options like
8BITMIME and SIZE keywords apparently are not being handled properly
by your new SMTP server.  Evidently, whatever NT subsystem handles
mail transference to your SMTP server is arguing over those
extensions.

But the "smtpmail" lib, which you are using, contains no use of the
extensions that I can see (looking at XEmacs' copy, anyway).  Perhaps
your SMTP server is reporting its argument over these extensions with
the next hop, contacted directly while your connection to your SMTP
server is still open.  Either way, your new SMTP server is the weak
link in the chain now.

It is generated by smtpmail-send-it when encountering unknown ESMTP
extensions.

To see what extensions are supported by your ESMTP server, you can try
a telnet on its port 25, followed by a "EHLO" command. On my company's
server, it looks like:

250-...
250-XEXCH50
250-HELP
250-ETRN
250-DSN
250-SIZE 0
250-AUTH LOGIN
250-AUTH=LOGIN
250-STARTTLS
250 TLS

and smtpmail-send-it complains about many of these Microsoft
extensions (like XEXCH50).
