Filtering with NewsProxy

NewsProxy Filter Main Page

 

Download NewsProxy (nfilter_120.exe) here.

This archive is a collaborative effort from participants in the alt.comp.freeware newsgroup for the purpose of archiving methods to filter unwanted posts from Usenet newsgroups using NewsProxy.

 

The following links point to files that the user can copy and paste to create the required nfilter.dat file used by NewsProxy. The user should save the pasted results to a text file and name it nfilter.dat, then place it into the NewsProxy directory along with the NewsProxy executable file. The files are intended to be used as starter templates to be edited, updated and customized to suit the user. Filters can be copied and pasted from different filter files to create a custom nfilter.dat file. The user cannot mix regular expression filters (regexp=on) with wildcard filters (regexp=off).


 

The following links point to filtering where the regexp option must be turned on.

 

o Link 1 This filtering link is used to eliminate posts from sporge news gateways based on the NNTP-Posting-Host: header field, using the drop method.

 

o Link 1a This filtering link is used to eliminate posts from sporge news gateways based on the NNTP-Posting-Host: header field, using the scoring method. It also shows how to exempt a user within a banned host from being dropped.

 

o Link 2 This filtering link is used to eliminate posts from sporge news gateways based on the X-Complaints-To: header field, using the drop method.

 

o Link 2a This filtering link is used to eliminate posts from sporge news gateways based on the X-Complaints-To: header field, using the scoring method. It also shows how to exempt a user within a banned host from being dropped.

 

o Link 3 This filtering link is used to eliminate posts that exceed a specified number of crossposts based on the Xref: or Newsgroups: header field, using the drop method.

 

o Link 4 This filtering link 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 following links point to filtering where the regexp option must be turned off. Filtering undesirable newsgroups without using regular expressions does not allow the fine-tuning needed to accurately eliminate the undesirable crossposts, and is not recommended.

 

o Link 5 This filtering link is used to eliminate posts from sporge news gateways based on the NNTP-Posting-Host: header field, using the drop method.

 

o Link 5a This filtering link is used to eliminate posts from sporge news gateways based on the NNTP-Posting-Host: header field, using the scoring method. It also shows how to exempt a user within a banned host from being dropped.

o Link 7 This filtering link is used to eliminate posts that exceed a specified number of crossposts based on the Xref: or Newsgroups: header field, using the drop method.


 

Eliminating GoogleGroups posts:

 

o Using regular expression (regexp=on)

* drop Message-ID:.*googlegroups.*

The newsgroup wildcard can be replaced with a specific newsgroup name if desired.

alt.politics.kooks drop Message-ID:.*googlegroups.*

The X-Complaints-To: header field can also be used:

* drop X-Complaints-To:.*google.*

 

o Using wildcards (regexp=off)

* drop Message-ID:*googlegroups*

or

alt.politics.kooks drop Message-ID:*googlegroups*

The X-Complaints-To: header field can also be used:

* drop X-Complaints-To:*google*


 

Eliminating MI5 posts:

 

o Using regular expression (regexp=on)

* drop Subject:.*[Mm][^a-zA-Z]*[Ii][^a-zA-Z]*5.*

 

o Using wildcards (regexp=off)

* drop Subject:*M*I*5*

(Not recommended since unintended posts may be dropped. Will also need to duplicate and modify this filter for lowercase.)
