Sounds fine to me....(since no one else is commenting :)

The whole idea of surbl relies on the fact that there is no legitimate way 
that a spam url would be found in a genuine message. This isn't too hard 
considering how obscure and obfuscated most spammer domain names 
are...they're not the kind of thing that you'd write by accident in casual 
conversation :)

However something obvious like example.com is something that can (and is) 
written in non-spam messages sometimes...so definately needs to go...
