New URI blacklists

URIBL has recently launched with four new blacklists of URIs.
The criteria are similar as those used by SURBL.
There are four lists currently available:
* black.uribl.com – Which is an aggresive list of known spammers. With a goal of zero False Positives.
* grey.uribl.com – Which lists people who spam and have legitimate uses. This will cause False Positives for some depending on your definition of SPAM.
* red.uribl.com – Experimental list for new domain registrations and mass moves between registries that are defined as spam supporters or facilitators. Use at your own risk.
* multi.uribl.com – Which checks to see if a domain is on any of the lists.
I added them to our filters last week and the results so far have been very good.
Instructions on integrating them with your existing SpamAssassin setup may be found here
There is also an easy to use submission form where you can report either URIs or full spam examples with the URIs.
