Sorry, my bad. Xnews doesn't do it. One of the other newsreaders I
have tried out did, can't remember which one though. I much prefer
Xnews.
Despite what it says in the manual, Xnews was updated to do this in
version 5.01.10:
" + Yes, Virginia, you can now score on non-standard headers such as
NNTP-Posting-Host. By non standard headers, I mean those that are
NOT included in XOVER) . As with everything Xnews, there are
caveats:
1) Your server must support the XHDR command. As I understand it,
most do. However, some servers (e.g., Typhoon) only support the
standard XOVER headers, so you still can't score on anything other
than the standard headers (subject, from, message-id, lines, xref,
and now, bytes).
2) It takes time to download those extra headers.
3) I don't save them in storage, so if you have
ScoreStoredArticles=1, scores with non standard headers will not
work on stored headers.
4) If you edit the score file while a group is opened and add one or
more non- standard headers, those scores will not take effect til
next time you open the group.
5) I'm sure I added a bunch of bugs."
So Xnews can score on non-standard headers, but it's dependant upon
the server sending that header. To see if the server sends it, you'll
have to telnet into your newsserver ( telnet news.blah.com 119 ) and
typing the command list overview.fmt . Many news hosts won't send the
non-standard headers due to the extra processing required, but it's
worth a try.
