incorrect sender

incorrect sender

[David Hedbor]

When I send mails with Gnus nowadays the sender is always
webmaster@animearchive.org (as demonstrated below). This is incorrect
since I use posting styles to set different from addresses. How can I
fix this?

MAIL FROM: <webmaster@animearchive.org>
250 <webmaster@animearchive.org>... Sender ok
RCPT TO: <licq@ctr.videotron.com>
250 <licq@ctr.videotron.com>... Recipient ok
DATA  (irrelevant headers and body snipped)
354 Enter mail, end with "." on a line by itself
To: licq@ctr.videotron.com
Sender: neotron@nyarlathotep.hedbor.org
From: David Hedbor <david@hedbor.org>
[..]
250 PAA00759 Message accepted for delivery
QUIT
221 pokey.animearchive.org closing connection

As you can see Sender is correct, and so is the From header. However
the MAIL FROM value is incorrect.

Two points:

First, this traffic is not generated by Gnus (if you got that from a
buffer, you are probably using smtpmail).  There is no way to make Gnus do
what you are asking because Gnus is not involved with the transaction.  It
has already washed its hands (metaphorically speaking) of the message by
that point.

Second, while the value might be considered inappropriate, it is correct
(canonical).  This is what is supposed to be there, specifically because
you are using non-canonical mailbox information in your RFC 822 headers.
Changing it would be `illegal' (cf RFC 821: SMTP, and its descendants).

Ok. Guess the problem lies in the value of user-mail-address which is
webmaster@animearchive.org. Now when I think about it, I realize I had 
this fixed until I upgraded to pgnus. using this:

(defun neotron-change-address ()
  (interactive)
  (let* ((head (message-fetch-field "From")))
    (setq user-mail-address head)
    (let (email (message-user-mail-address))
      (setq user-mail-address email))))

(add-hook 'message-send-hook 'neotron-change-address)

That doesn't seem to work anymore. In any case the problem remains -
when using posting styles Gnus doesn't supply the mail sending agent
with a correct sender, which in this case would be setting
user-mail-address to the correct value.

Why would it be the correct sender? I am not sending it as
webmaster@anime, so why on earth would that be the correct one? I
don't understand what you're talking about, to be honest. It's the
wrong address.

Are you running your emacs as user webmaster on machine anime?

If you are logged into the machine with the canonical name 'anime.org' with
login 'webmaster', then your canonical mailbox is 'webmaster@anime.org'.
This is what is inserted in the envelope (MAIL FROM).  It only seems wrong
becuase you don't understand the complexity of mail handling.

Anyway, if it is invalid, your site's MTA should be configured to rewrite
outgoing information, either through masquerading or genericstable.

As an aside -- I noticed the same problem and (although I didn't look
at it in depth) if I use a literal "From" field in my posting style
rather than the name/address stuff it seems to exhibit the correct (or
should I say "desired") behaviour.

e.g. do this:

(setq gnus-posting-styles
   ...
	 ("From" "Jeff Senn <senn@maya.com>")
   ...

rather than:

(setq gnus-posting-styles
   ...
	 (name "Jeff Senn")
	 (address "senn@maya.com")
   ...

I do this already and it doesn't seem to work.

It is a different problem.  David is complaining about RFC 821 (SMTP)
envelope data, not RFC 822 headers.  As Gnus has no control over envelopes,
there is nothing Gnus can do about it.  This is the purview of the local
MTA or smtpmail, whichever David happens to use.

Since I am using smtpmail which gets that data from user-mail-address, 
it would be safe to assume that it would be the right thing for Gnus
to change the value of that variable, ne? 

As it turns out, it seems like Gnus already does to this. The variable
is however made buffer local to the message buffer, so it isn't used
when sending mails. 

I "fixed" my problem by setting the global version of that variable to 
neotron@nyarlathotep.hedbor.org.

Hmmm... skim through smtpmail.el....

Interesting.  It changed since the last time I looked at it.  smtpmail now
uses user-mail-address instead of catenating (user-login-name) +
(smtpmail-fqdn), which is what sendmail does.

Yes, I understood that -- of course I missed the part of my .emacs where
I "outsmart" smtpmail [as well as myself apparently... :-) ]
