Postfix tools for the Black List Daemon

BLD stands for "black list daemon" and is intended to build blacklists using simple rules based on a maximum number of submissions of the same IP address during a minimum time interval. BLD was primarily designed to fight against dictionary-based spams (by making the MTA report to BLD any host that tries to send a mail to an unknown user) but can be used by any application that needs a blacklist based on connection rate limits. This package contains the tools dedicated to Postfix.
