My experience is that the only additional filtering NFilter
offers is on the XRef.

Have you tested to see if you can filter on 'organisation',
'followup-to', and 'x-newsreader'?

I'd be surprised if you can, but would be interested to see
you test and report back

Thx for that. My feeling/experience remains that NFilter can only
filter on the overview - all else, including NFilter's own
documentation, is wishful thinking.
The overview looks to be standard. The example given in NFilter docs
corresponds to the overview I recently checked on five newsservers:

Subject:
From:
Date:
Message-ID:
References:
Bytes:
Lines:
Xref:full

Xref is seriously useful, I'm currently experimenting with flagging
googlegroups on the MID, and I can imagine circs in which the Refs
could be useful.

It would be nice to filter on XHDR though... *sigh*

Yes, indeed.

FWIW, may favorite (pr0n from HK):
* drop References:*netvigator*
(this sometimes fails; I'm not sure why)

I could swear I have seen posts in news.software.readers confirming
that NFilter (at least some version of it) does work with XHDR (or
HEAD, either would work). Maybe asking about it over there would turn
something up, I dunno.

Yeah, those are indeed the standard for the overview database. Xref is
optional but highly recommended, and AFAIK all servers that have an
overview database include it.

Filtering on References is most useful when you want to filter all
replies to a poster or everything downthread from that poster.

It's not a proxy but a local server which acts as a client to remote
servers. If I didn't use it for anything else (I do), it would be
worth it for the filtering capabilities alone.

Yep. All over usenet for years you can read posts confirming that
NFilter will do this and that.
What you *never* see is anyone actually doing it.

Yet somehow it manages to retain its reputation. No other app that
promised so much but delivered so little would keep its reputation in
this way

It's years since I looked at Hamster, and that was just to get
multiple pops into Agent. Ikeep meaning to go back...

One problem I see on this newsserver very often: it does not
report _all_ Xref's.
Of course, I cannot tell who/what is dropping the missing NG's.

The Xref: header only includes the newsgroups listed in the Newsgroups:
header that are also carried by your own newsserver.

I've used Nfilter to drop cross-posts using the Newsgroups: header
where a troll was consistantly cross-posting to a newsgroup
not carried by news.cis.dfn.de, but as Newsgroups: is not
part of the standard overview it slows downloading the headers.

I can confirm that Nfilter does work with XHDR and will
successfully filter on headers that do not appear in the
Overview - subject to the news server supporting the XHDR
command of course, which as I posted previously this
news server does.


However, as far as I'm aware Nfilter does not use the
HEAD command if XHR is not supported by the server.
My guess is head isn't used because downloading all
headers could be time consuming and tempt trolls
to make them as large as their news server would permit...

Thanks. I'll tinker w/ it.

Follow up:

Quite a lot of testing of NFilter over the last two days has given
perfect results on non overview headers on news.individual.net

*happy now*

Interesting. What server?

The one you are now using (individual.net) and a very few others
(in fact all the servers I've tried - probably lucky I guess).

There is a minor bug in Nfilter, that can cause problems.
Invalid filters can either cause it to misbehave - usually with an
invalid page fault or else to not filter as expected. I've also found
it is usually necessary to shut Nfilter down and restart it
after updating nfilter.dat .

Thx. I've put a daft amount of work in over the last couple of days
with very good results. I have found that the main mistake I have been
making is to test using 'flag' which behaves oddly when sorting by
thread. I'll check the newsgroup field later, though I assume it will
work since i have successfully filtered on path, organisation, FU2,
X-Newsreader, etc recently.
Thanks for the feedback.
