• Dear Pleskians! The Plesk Forum will be undergoing scheduled maintenance on Monday, 7th of July, at 9:00 AM UTC. The expected maintenance window is 2 hours.
    Thank you in advance for your patience and understanding on the matter.

Input Mail-Headers?

Just follow that recipe!
I don't agree that such info is sensitive, but hey, everyone has their right for paranoia.

There's no way (AFAIK) to prevent Plesk from rewriting main.cf and master.cf, but it doesn't do it as often as it did in the past.

I have a monitoring system that will alert me that this file has changed.
I have a cronjob that will save the complete /etc/postfix in a compressed tar-file if it ever changes.
It has the advantage that you will find out if Plesk has been improved or that it just killed your custom setup.

cat /etc/cron.hourly/taretcs
Code:
#!/bin/bash

tarfolder /etc/postfix
tarfolder /etc/courier-imap
tarfolder /etc/dovecot

cat /usr/local/sbin/tarfolder
Code:
#!/bin/bash
