Note: The collectd plugin Collectd::Plugins::RedisClient could be used to record counter values.
Botnet
Botnet looks for possible botnet sources of email by checking various DNS values that indicate things such as other ISP's clients or workstations, or misconfigured DNS settings that are more likely to happen with client or workstation addresses than servers. Mirrored for educational purposes with applied patches, as it seems abandonded and nowhere to be found. No other changes are done. As the plugin has some interesting idea's there might be a (partial) rewrite in the future.

::Plugin::iXhash2
iXhash2 is an unofficial improved version of iXhash plugin for SpamAssassin, adding async DNS lookups for performance and removing unneeded features. It's fully compatible with the iXhash 1.5.5 (https://sourceforge.net/projects/ixhash/) implementation. It computes MD5 checksums of fragments of the body of an e-mail and compares them to those of know spam using DNS queries to a RBL-like name server.
