Projects / BLD


BLD stands for "blacklist daemon" and is intended to serve a blacklist. The blacklist is built by simply inserting IP addresses or by using submission rate limits based on a maximum number of submissions of the same IP address within a minimum time interval. A BLD cluster can be built by configuring the daemon to notify other similar daemon(s) every time an IP address is added to the blacklist. BLD was primarily designed to fight against dictionary-based spam (by making the MTA report to BLD any host that tries to send email to an unknown user), but can be used by any program.
