My mail server is on Ubuntu and I use SSH, Plesk and Warden Anti-Spam wiith Amavis to Handle my settings and filters. I'm trying to hide some sensitive data unnecessary and labels from Incoming and Outgoing Email Messages headers.
- For example I want to hide/change ubuntu
- Tying to Ignore/disable X-Spam-Status, X-PPP-Message-ID, X-Virus-Scanned and possible "none-required versions".
- Need to prevent messages with spam score over 13 from reaching the Junk Mail folder
Incoming

I've also did the
ServerTokens Prod
ServerSignature off
After necessary postmap , postfix check, systemctl reload postfix I still have issues and didn't reach the goal(s).
Any Suggestions?
