Description-en: 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.
