I checked out squid and found that it did not contain the latest Spamming domains such as (at this moment - Volumedrive.com)

I'm looking for a way to add dynamic, up to the moment IP blocking based on up to the minute blacklists of IP addresses from which spam has been sent.

These are the same IP addresses that can be found if you go to mxtoolbox.com and enter the IP address in the Blacklist search box.

Anyone know how to do this on Ubuntu 8.10 Server?
