As promised, today I've put my local rule monitoring script on my website along with my spam killer. They are downloadable from:
http://www.gregorie.org/computing/index.html The downloads you want are all referenced under 'Topics': spamscan - the rule monitoring Perl script spamkiller - deleted messages marked as spam. Its C source. It requires the environment support library to compile. I hope these are useful. Contact me off list if you have queries about them. Martin
