MTA STS

[mehdi05]

Hi everyone,


I would like to enable MTA-STS to secure email communication on my mail server. The server is running on Debian 11 as a VM hosted on Proxmox.


My question is simple:
How can I properly implement MTA-STS in this setup?
Should I install a specific plugin or resolver on the VM?
Are there any best practices to follow to avoid service disruption (especially with Postfix)?


Thanks in advance for your help!


Best regards

Just FI,
Everything is already configured and functioning correctly on the HTTPS server and DNS side; I only need guidance on the Proxmox side.
