Topic: Server hostname & mail headers
I want to set up a mail server to host multiple domains and users. Mail will be handled only for the hosted domains, not for the server domain.
The servers FQDN is mail.example.com
One of the hosted domains is fubar.org
Another is fizbiz.com
If someone receives an email from a user at fubar.org, the email headers should a path to fubar.org, NOT including mail.example.com
Is this possible? If so, how do I set it up?
