greylisting implementation for Postfix
This package provides a policy server for Postfix to implement "greylisting". Greylisting is a spam filtering method that rejects email from external servers on the first try. Spammers don't usually retry sending their messages, whereas legitimate mail servers do. While Postgrey is designed for use with Postfix, it can also be used with Exim.
