Question How to Hide the Server IP in Sendmail?

Server operating system version

Rocky Linux 8.6

Plesk version and microupdate number

Hello,

Is there an easy method to hide the server X-SOURCE-IP in sendmail or change it to the domain?

I want to secure my server further by hiding the server IP from the public.

This is not possible to do, because on the receiving end in the mail hop log that is inserted into the header of each received mail there is always a line like "Received from ... (ip address) by (local server)" etc. So even if you were able to remove any headers mentioning your IP address, the first hop between your server and the recipient will insert the IP address into the header.

So basically, set up an independent server and send all server and Sendmail emails through it.
