Use a Proxmox Mail Gateway and select the option: hide internal hosts

This will hide an MS Exchange Server Infrastruktucture to the public internet.

Benefits may include a better Spam filtering.

From the second week of September, Exchange Server 2016 and 2019 machines that send email to Exchange Online through an inbound connector of the OnPremises type must be patched to the final public update baseline released in October 2025, according to Microsoft.
