Any billing, root, postmaster, etc... messages that claim to be from his system have to be generated from their management IP space. You may be able to phish their customers by sending them bogus messages of this sort that claim to be from other sites or facilities, but you won't be able to phish his customers by sending them messages like this that claim to be from his system.I applaud his move, and wish more groups did the same.
It would have been better if he had just installed SPF, and published DNS records for his own domain, and rejected them based on that. Then other people receiving forged emails with his domain would also be able to just drop those emails. Paul
