They are massively different both in scope and intent. Among other things:

1. "Address registries" levy fees and impose effective monopoly control
  over address space. The RBL does not impose any effective monopoly
  control, it is not a fee-paid-service, and in fact neither is SMTP
  traffic exchange in the norm.

Fees are irrelevant. A monopoly is not a monopoly if they don't charge
people money?

2. You can always go somewhere else to relay (or send) your email if
  you find yourself RBLd. You can't go somewhere else to get address
  space (back to central control again).

That is only a difference in scope of deployment. It is still, as Derek
argued, the "Same basic principle". What if the same number of people had
confidence in the RBL as in ARIN's authority to delegate addresses?

3. RBL-free access is not an essential facility. IP address space is.
  This is an incredibly important distinction, in that it triggers all
  kinds of special treatment from the US Government when it comes to
  non-discriminatory access to that facility.

You cannot send mail if the whole world has RBL'ed you. That's arguably

4. Historically speaking, nobody "owns" lists of acceptable SMTP
  relaying conduct (or lack thereof). Historically speaking, people

I "own" (RFC2008 sense) ARIN approved IP addresses. I also "own" RBL
approved domain names (that is, they are not on the RBL). If domain
names were as limited a resource as IP addresses are, my domain names
would be as precious as my IP addresses, and an RBL domain name would
have the same value as a rogue block of IP addresses.

5. Collusive conduct which is designed to and/or acts to restrain trade
  and limit competition is frequently unlawful in the United States.
  Keeping your speech off my computer is not unlawful - in fact, it is
  my private property right to do so. However, were I to *COLLUDE
  WITH OTHERS* to put you out of business (or increase your cost
  of doing business) by refusing to accept your traffic, you'd have
  every right to sue my ass off - regardless of whether or not I am
  doing it via SMTP or at the packet level.

Then you have to decide whether the action is being done with the
intent of restraining trade and limiting competition. That would depend
on the case. Cooperation to use the RBL might just as likely be found
by a court to be illegally collusive as cooperation to ignore somebody's
route announcement.

Really, it is the "same basic principle".


You're right. BTW, I wasn't arguing for the RBL :slight_smile:

*Privately maintained and non-published* (to other than customers) lists
used only by you are one thing. Public blacklists are another, and can
under certain circumstances get you in serious trouble.
