Persistent editing of postfix files

[VimManiac_Pvt._Limited]

Hi Guys, I want to put custom values in /etc/postfix/main.cf, but I'm afraid plesk would overwrite them during upgrade. How can I safely add custom values to main.cf and preserve them duing plesk updates?

Actually it depends on Postfix settings. Some of settings, especially which can be modified in Plesk UI will be overwritten. But some of settings will not.
Anyway, you may describe your business case in this feature request - https://plesk.uservoice.com/forums/...06-allow-customization-of-etc-postfix-main-cf
We need to know:
- what sort of modifications you need?
- for what these modifications?
