Grappy - Greylist daemon in Python

NOTE - Maintainance of this software has been transfered to Kyle Lanclos You can find the new project website at http://grappy.lanclos.org/.

Many thanks to Kyle for taking over the role as maintainer.

I no longer make active modifications to this software. It is still available for those who want to use it but I personally don't use it any more. When I do greylist development it is now on the Helm greylist server which is available at https://roundup.it.su.se/confluence/display/helm.

This package is a postfix policy daemon which implements grey listing functionality. This is just one of many implementations. More information on the greylisting technique is available at http://projects.puremagic.com/greylisting/index.html

Features of this implementation are:

Written in python.
Uses a mysql och postgresql database back end, which makes it suitable for cluster mail server environments
Written for high performance environments. It uses threads and a database connection pool for high throughput
Supports separate whitelists for sending ip, sending email and receiving email
Supports ipv6
