Mail-Followup-To header

Mail-Followup-To header

[Gary]

I asked about this in a thread - OP @ M-ID: <i3bp09$qe0$1@dough.gmane.org>
- on the general emacs ml but never really got it properly sorted out.

In summary: I read and post to various mailing lists via the gmane
mail2news/news2mail gateway. That is, when I post, I am doing so in a
manner that gnus thinks I am posting to a newsgroup, not a mailing list,
so it doesn't set Mail-Followup-To. Jim Crossley suggested simply using
posting styles to force the generation of the proper header, so I tried,
for example:
,----[ config-nntp.el ]
| ...
| (push '("gmane.emacs.help"
| ...
|          ("Followup-To" "gmane.emacs.help")
|          ("Mail-Followup-To" "help-gnu-emacs@gnu.org")
| ...
`----

but the articles still end up without those headers. If I add the
headers manually, the Mail-Followup-To survives, while Followup-To is
transformed (by gmane I think) to Original-Followup-To :(

Why does gnus decide not to set (or strips) the headers I specified in
the posting style? Is there any way to avoid the manual step?

Gmane transforms Followup-To to Original-Followup-To, so this is not
under Gnus' control.

Bye, Reiner.

Yeah, I gathered that, thanks. I'd still like to know why, when I add
the above values to my posting styles, the headers aren't posted, but
are when I set them manually (even if gmane happens to mangle one of
them).

Well, apparently adding them to posting styles isn't enough, one must
*also* add them to message-required-news-headers:
,----[ .gnus.el ]
| (setq gnus-select-method '(nntp "news.gmane.org"))
...
| (push '("gmane.test"
...
|          ("Followup-To" "gmane.test")
|          ("Mail-Followup-To" "whatever@example.com")
|         )
|        )
|       gnus-posting-styles
| )
| 
| (setq-default
|  message-required-news-headers (append
|                                 message-required-news-headers
|                                 (list '(optional . X-No-Archive)
|                                       '(optional . Mail-Copies-To)
|                                       '(optional . Followup-To)
|                                       '(optional . Mail-Followup-To)
|                                 )
|                                )
| )
| (setq-default X-No-Archive '"Yes")
| (setq-default Mail-Copies-To '"never")
