The latest beta version comes with an invalid PTR sample file. That sample file contains a couple of regex that I posted on this forum some time ago. A couple of these regex were tailored to my site and I don't want to punish these ISPs for not checking their customers or managing outbound mail traffic well enough.
Blocking Wanadoo is a matter of location. So that should perhaps also should be deleted from the defaults list.
By the way the most effective part of this list of regex is from this site: http://www.gabacho-net.jp/en/anti-spam/anti-spam-system.html It is very powerful at blocking dynamic IPs. However from time to time it will also block badly configured mailservers without a proper Reverse DNS record (often Exchange Servers at small businesses).
