Introduction

The Postscreen Postfix service can be enabled to filter out undesired SMTP clients on initial connection to the mail server. Postscreen uses certain criteria (static white/blacklist, DNS Block List queries, communication analysis) to allow or deny connections for a given SMTP client.

This role can be used to enable and configure Postscreen in a Postfix installation managed by the debops.postfix Ansible role. It does not configure Postfix directly on its own.

Installation

This role requires at least Ansible v2.3.0. To install it, run:

ansible-galaxy install debops.postscreen
