How to change this Client to something more readable and also hide the information that we are using mailcow or replace with our company name or something?
When we sent mail it appears that the source contains this line:
Received: from 9512f887d907 (mailcowdockerized-sogo-mailcow-1.mailcowdockerized_mailcow-network [172.22.1.248])
Is there any way to replace it with something like: client=sogo-mail or somehing else since we want to do this for security reasons too, to not disclose in public what Mail Server we are using…?
