That will break other things. SPF and forwarding don't go well together.
If you really need to do it, there is supposed to a standard for rewriting
the envelope sender address that could be used to forward bounces back
to redhat.com via fedoraproject.org.
The recipient could also relax the checks on their end and accept email
from fedoraproject.org servers.
