Rspamd is fast, lightweight and modular spam filter. It is designed to work with big amount of mail and can be easily extended with own filters written in Lua or Perl.
To build rspamd just download cmake, gmime and then type
cmake .
followed by traditional
make
sudo make install
Example config would be in $PREFIX/etc/rspamd/rspamd.conf.sample You can edit it and put in $PREFIX/etc/rspamd.conf to use with rspamd (or you can specify config file with -c option) For using rspamc client you would need only perl (5.8 works fine).
