day of week in Date header?

day of week in Date header?

[Kai Großjohann]

My Date header seems to contain the day of week, whereas most other
Date headers generated by Gnus don't.

Where does the day of week come from?

The Date headers are generated by message-make-date. Are you using a
modified message-make-date?

No.  Hm.  My outgoing messages don't have a Date header before I hit
C-c C-c, but that's normal for message-generate-headers-first being
nil, right?

And message-required-mail-headers contains `Date'.  Most amazing.
Hm.  Could it be that sendmail is frobbing the Date header?

Hm.  I've got the following section in /etc/mail/sendmail.cf:

/----
| #########################
| #   Format of headers   #
| #########################
| 
| H?P?Return-Path: <$g>
| HReceived: $?sfrom $s $.$?_($?s$|from $.$_)
| 	$.by $j ($v/$Z)$?r with $r$. id $i$?u
| 	for $u; $|;
| 	$.$b
| H?D?Resent-Date: $a
| H?D?Date: $a
| H?F?Resent-From: $?x$x <$g>$|$g$.
| H?F?From: $?x$x <$g>$|$g$.
| H?x?Full-Name: $x
| # HPosted-Date: $a
| # H?l?Received-Date: $b
| H?M?Resent-Message-Id: <$t.$i@$j>
| H?M?Message-Id: <$t.$i@$j>
\----

Does that mean that the Date header is stomped over by sendmail?  Hm.

All these settings are the same as mine. message-make-date is called
after you hit C-c C-c. What is the output of (message-make-date)?

(message-make-date)
=> 05 May 2000 17:06:46 -0400

(message-make-date)
=> "05 May 2000 23:56:06 +0200"

I'll debug-on-entry that function now.

I have now done this, and verified that message is indeed inserting
the right Date header into the message.  So I think that something
outside of Gnus, presumably sendmail, is twiddling with that header.

Thanks.

I get this list from the news-server at sunsite.auc.dk, and I know that
it strips away the original date-header and inserts a new one -- this
happens to mailing list messages and normal Usenet messages, too. The
news-server at my ISP also does this.

I don't think this behaviour actually violates rfc-1036, but it /is/
wrong according to grandson-of-1036.

Cheers,

It violates a MUST in the current USEFOR draft, for what it's worth, and
has been the cause of spews in the past.

I'm subscribed directly to the mailing list and still see the day of
week.  Hm.
