Started by me and Brad's being hacking on this as well. It's not yet perfect but seems in good enough shape to import and continue to work on in-tree, any OKs to do that?
-- -- -- Rspamd is an advanced spam filtering system that allows evaluation of messages by a number of rules including regular expressions, statistical analysis and custom services such as URL black lists. Each message is analysed by rspamd and given a spam score. According to this spam score and the user's settings rspamd recommends an action for the MTA to apply to the message- for example to pass, reject or add a header. Rspamd is designed to process hundreds of messages per second simultaneously and has a number of features available. -- -- -- (This is the daemon/client, for filtering directly in an MTA there is also a milter but that hasn't been ported yet).
