====== pflogsumm Mail reports ======
pflogsumm is a simple yet great mail summary reporting tool.  You can install it using aptitude.

===== Features/Tasks and Limitations =====
  * Emails report via cron
  * Keeps 40 days worth of reporting at /var/log/postfixrep
  * Limitation: Since log rotate does not do a daily rotation, reports will overlap!
    * This is not an issue with systemd
  * Update email: system@example.com

===== cron job to do daily reporting =====
Create a directory 
<code bash>mkdir /var/log/postfixrep </code>

==== Cron Script using systemd/journalctl ====
<code bash>
#!/bin/bash
#
# Daily Postfix Log report
#
TS=$(date +%Y%m%d_%H%M%S);
