ACL Policy Daemon is a program that communicates with the Postfix MTA using the
Policy Delegation Protocol implementing an ACL (Access Control List) system,
making very easy to improve and create nice controls on your e-mail traffic.
You can use it to verify SPF records to.

The logic behind apolicy is simple, you define some rules, then you combine
them, if all of them matches, apolicy will send an action for that combination,
defined by you to. Take a look on what you can apply rules using apolicy's
ACLs. Some of them you already can do with Postfix, but they are sequential. In
pure Postfix you can not combine rules.

It is developed using Python and has no other dependencies and licensed by GPL
version 2.
