Filtering-with-NewsProxy Page

The following nfilter file is used to eliminate posts that are crossposted to specified undesirable newsgroups based on the Xref: or Newsgroups: header field, using the scoring method. The newsgroup wildcard can be replaced with a specific newsgroup name if desired. Edit and update as needed.

Place desirable groups at the top and give them a low score. Add undesirables as you discover them and give them a high score. Drop all messages with the high scores. There is no need to limit the number of crossposts.

Note: There is no reason to list the a particular desirable newsgroup as long as no part of its name appears within the undesirables filter list. For example, if you wanted to retain comp.sci.kooks but not other kooks newsgroups, you'd need to add that newsgroup to your desirables list per these examples.

If your news server can read the Newsgroups: field, that would be better than using the Xref: field since the Newsgroups: field will contain *all* the crossposts, whereas Xref: contains only those crossposts your news server recognizes.
