Chris is very knowledgable as sysadmin, but this has nothing to do
with him since he's neither working for Red Hat, nor does this have
anything to do with the servers he's administrating.

Yes, I'm sending mails using a non-Red Hat smtp server since I'm neither
sitting in the office, nor is this mail in any way confidential.

This is a valid scenario.  It's a valid mail address and a valid,
non-spam smtp server.  This only shows again how ill-conceived the SPF
idea is.
