PostPolicy: Postfix Policy Server in Ruby

PostPolicy uses ACL system, which allow administrators to create rules based on mail source. Unlike simple Postfix policy restrictions in PostPolicy one can create very complex rules against incoming mail. PostPolicy is built on top of eventmachine, event-driven network library used for critical networked applications.

PostPolicy is under heavy development so don’t expect too much at the moment ;)
