There is no SPF record for centos.org

If one can be added then this sort of fakes can be prevented. Anyone
using the centos.org domain in email should login to a centos.org server
to send out email that way.

I know it works because that is how I send out email from my own domain.
All family members need to use the central server as relay to send out
email with the family domain. And they can only authenticate using TLS
and SASL.

Hugo.
