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.

those spam emails and convert them into SpamAssassin rules
automatically (Note: When I say automatic, I still expect a human to
