PSLOGSCAN

A simple log file scanner for the Postfix Postscreen service. This script gives an overview of how Postscreen is performing. Written for /bin/sh Bourne Shell.

Initially tested on FreeBSD 8.4 and Postfix 2.11.1. It has run fine on interim versions of FreeBSD and Postfix. Currently running with FreeBSD 13.2 and Postfix 3.6.2.

Read the comments in the script to see what options you may need to tweak.

Update, February 6, 2021: I no longer maintain or update this script. There's an updated version (v1.9) that pulls some configuration parameters from main.cf using postconf, negating the need to enter some of those parameters manually.

The new home for pslogscan.sh is dmdmdm on github

Thank you for your interest in pslogscan.sh.

Sample output, showing Postscreen rejecting about 18% of the incoming mail.
