Most systems that I'm familiar with nowadays have the users put spam
emails that manage to get past the filters into a special folder
(directory) so they can be examined, in order to make the spam filter
system more effective. In pursuit of that Idea, I've written urlx.

Urlx is designed to extract urls, both clear and obfusticated, from
those spam emails and convert them into SpamAssassin rules
automatically (Note: When I say automatic, I still expect a human to
apply a sanity check somewhere).

Urlx is not yet released to the general public, but if you're
interested in helping test, please drop me an email.

Please note - Due to the intense volume of spam, we have installed
site-wide spam filters at catherders.com. If email from you bounces,
try non-HTML, non-encoded, non-attachments,
