He has no standing to pursue a legal challenge. He has no right to
deliver mail to a server. The issue is whether he has a contractual
obligation to his users to accept mail sent by Ed's server -- only those
users have any standing.

He didn't really say anything that implies that. What do you mean,
"the" ISPs? He's acting as one too.

Lots of people's users think it *is* a service.
Once again: nobody has any obligation to Ed to accept mail he sends.
They may or may not have an obligation to their users to accept mail
they wish to receive.
