JANET DNSBLs

JANET has its own copies of two leading DNSBLs:

• Spamhaus Zen lists
• MAPS RBL+

DNS Block Lists are a well-established technique.  They identify sources of e-mail abuse as lists of IP address blocks, enabling JANET organisations to quickly and easily reject a high proportion of unwanted e-mail.
