ACL Policy Daemon (apolicy for short) 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. What can be done with ACL Policy Daemon:
- Greylisting
- Flexible storage, use memory for fast responses or disk for high persistence
- SPF validation
- Control messages by day/time
- Variable message size limits per domain or e-mail
- Multiple RBL checking
- Reject a message only if the client's IP is listed on more than one RBL at the same time
- Small learning curve
Syntax heavily inspired by the Squid HTTP proxy ACL system
Various ACLs to use and combine
New features are planed on the Roadmap.
It is developed using Python and licensed under GPL version 2.
