Here's a python script to increment an emails spam score. I call it (potentially several times) after SpamAssassin and before final delivery.
A little python script that parses your procmail.log and shows where the last 20 emails got filed.

My xorg.conf let me down after my upgrade to FC5. I have a Logitech USB MX310 and this is how I got my back/forward buttons to work in Firefox.
