Hi Steve.

I've noticed one strange thing.
I run a few MX servers for the company I work for.

Two of them are running MailScanner with an older version of 
SpamAssassin (v 3.2.5)
One of them is running MIMEDefang with SpamAssassin 3.3.1

On the MailScanner boxes, your plugin triggers the HAS_SHORT_URL rule 
along with a number of the other SHORT_URL_* rules.
So it is working very effectively there.

But on my MIMEDefang host the plugin has triggered 197 times over the 
weekend with the HAS_SHORT_URL rule, but none of the the SHORT_URL_* 
rules fired at all.
So it only adds 0.001 to the overall score which isn't enough to ban the 
bad emails.
I'm not really sure what to check, but I'll start researching now to see 
if I can find why.
