Input Mail-Headers?

[omexlu]

Hello,

How can i implement this in plesk:
Remove sensitive information from email headers with postfix - major.io

I want to skip header informations and do the change on plesk that it is update safe?

Thanks

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

#!/bin/bash

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

cat /usr/local/sbin/tarfolder

#!/bin/bash

# Strip last slash..
