There's no reason why one couldn't build a comparable model for mail, with the SMTP speciality service provider offering SMTP transit to a base of trusted customers. This comparatively small number of SMTP speciality provider would then maintain good relations (peerings) with the

There are, however, three very big problems. First, it forces people to pay for services that they don't pay for today. Businesses often pay, not for services, but for accountability. They want someone else to take responsibility for a problem even if it costs them more money than taking

If the BGP peering side of the business can sort out all of this stuff, then why can't the email side of the business do the same, or perhaps, do even better? It's not comparable, as has been explained several times to you. Perhaps you have never been involved in BGP peering? Let me

Of course, there's already one application-level messaging protocol that relies extensively on arranged peerings: Usenet. Usenet doesn't rely on a *full* N-way mesh of arranged peerings, it relies instead on a core of fairly well interconnected backbone or core news sites who've agreed to do

Here's a simple mechanism which has not yet been tried seriously. Email server peering. This means that an SMTP server operator only accepts incoming mail from operators with whom they have a bilateral email peering agreement. This has been tried in the X.400 world. I wouldn't exactly say
