Well, ALL RBLs list some IPs that don't fit their criteria. Mislistings are a fact of life for every RBL operator. In general I find the SORBS DUL quite accurate, unless your SA trust path is broken and SA winds up checking source IPs instead of only checking the delivering relay. (By default you WILL suffer from this problem if you have a NATed mailserver.) However, rather than theorizing about how SORBs DUL works, why not just read their FAQ: http://www.us.sorbs.net/faq/dul.shtml In theory, all dynamic IPs will be listed, and all static will be excluded. Reality is significantly less perfect than theory. However, the FAQ will also point you in the right direction for fixing errors. Large ISPs can get an ID to directly register information, end users can submit information via a web mail form for consideration by the SORBs operators.
