This enhanced version of rbldnsd provides enhanced logging features:

• IP address anonymization (via SHA256 hashing)
• GeoIP lookup of client IP addresses
• Contents of the reply RR

Note that this version rbldnsd uses a tab character (\t) to separate the log fields, since the new GeoIP fields may contain spaces.

The installation procedure is the same as with the stock version of rbldnsd:

./configure && make && make install

Additionaly, the configure script supports the options anonymize and geoip. Anonymization requires OpenSSL and GeoIP lookups require libGeoIP. If your system provides these dependencies, these options are automatically enabled.

The new features require explicit activation on the command line:

• -z: enable IP address anonymization
• -g: enable GeoIP lookups
• -L: enables logging of answer details the logfile
