Using Perl spam filtering with NNTPRelay 1.1b4

1. Install perl onto your news machine.
2. Find the perl filter you wish to use. (CleanFeed etc...)
3. Edit filter for per site settings.
4. In config.txt add the following entry (of course with relevant paths):
   ExternalFilter=c:/perl/bin/perl.exe f:/news/perlfilter.pl
5. Restart NNTPRelay.

*Note* NT requires an addition to make perl filters work properly with NNTPRelay:

binmode(STDIN);

This should be placed so as to run before the perl filter starts up.
