# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

postgrey: postgrey (Postfix Greylisting Policy Server)
postgrey:
postgrey: Postgrey is a Postfix policy server that implements greylisting. When
postgrey: a request for mail delivery is received by Postfix via SMTP, the
postgrey: triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first
postgrey: time that this triplet is seen, or if the triplet was first seen less
postgrey: than 10 minutes ago, then the mail gets rejected with a temporary
postgrey: error. Hopefully, spammers or viruses will not try again later, even
postgrey: though such behavior is required per RFC.
