Hypertext Mail Protocol (a.k.a. Stub Email): A Proposal

Back in the days of dial-up modems and transfer speeds measured in hundreds of bits per second, unwanted email messages were actually felt as a significant dent in our personal pocketbooks. As increases in transfer speeds outpaced increases in spam traffic, the hundreds of unwanted emails we received per week became more of a nuisance than a serious financial threat. Today sophisticated spam filters offered by all major email providers keep us from seeing hundreds of unwanted emails on a daily basis, and relatively infrequently allow unwanted messages to reach our coveted Inboxes. So, to some degree, the spam problem has been mitigated. But this "mitigation" requires multiple layers of protection and enormous amounts of continually-applied effort. more

Internet Governance: An Antispam Perspective

All those Internet Governance pundits who track ICANN the way paparazzi track Paris Hilton are barking up the wrong tree. They've mistaken the Department of Street Signs for the whole of the state. The real action involves words like rbldnsd, content filtering, and webs of trust. Welcome to the Internet! What's on the menu today? Spam, with some phish on the side! We've got email spam, Usenet spam, IRC spam, IM spam, Jabber spam, Web spam, blogs spam, and spam splogs. And next week we'll have some brand new VoIP spam for you. Now that we're a few years into the Cambrian explosion of messaging protocols, I'd like to present a few observations around a theme and offer some suggestions. more

EFF on Goodmail: Further Confusing an Already Confused Issue

Cindy's piece on the EFF website seems to be a bit of a pastiche, with elements taken out of various articles (some outright wrong, some merely misinformed) that have been doing the rounds of the media for quite a while now about Goodmail. She started off comparing AOL and Goodmail with the old email hoax about congress taxing email. That same line was used in a CircleID post by Matt Blumberg, CEO & Chairman of Returnpath... Various other quotes from different places - Richard Cox from Spamhaus on CNN for example. However a lot of the quotes in those articles are being based on wrong or out of context assumptions, starting with one that goes "AOL is going to remove all its existing whitelists and force people to use Goodmail". more

Challenges in Anti-Spam Efforts

Without commenting on the particulars as they relate to Goodmail -- especially since I am on the advisory board for Habeas, a competitor -- let me note that public discussion is largely missing the nature of the current Internet mail realities and the nature of the ways we can deal with them. There are two articles in the current issue of the Internet Protocol Journal, of which I wrote one, that provide some useful background about this reality. Simply put, Internet mail needs to sustain spontaneous communications... more

IDNs and IE7 and the Coming Storm

If you're brave, today you can finally download the Internet Explorer 7 public beta. Why should you be interested? Not because the browser's wonderful. It isn't -- initial reports are that it's not ready for prime-time. But you might be interested to know that as of today, users of IE will be able to use internationalized domain names (IDNs). ...Many other browsers are already IDN-capable, including Firefox, but most people in the world use Explorer. Think China, Japan, India. Think most of the world's population... Think of millions of new Internet users working in their own language, customers for commercial goods and services. But think also about intellectual property nightmares, think about phishing, think about whether there's one interoperable Internet, or several Internets acting very weird. These issues and others will become big news when people start using IDNs massively -- and with support from Internet Explorer, that's about to happen. more

Internet Wars

A couple of days ago the BBC reported that a document called the Information Operations Roadmap (PDF) had been declassified and that it contained some pretty interesting stuff. The American dominance over the Internet, recently manifested by its unwillingness to hand over some of the critical control to UN-organizations, may have another side to it. more

IPv6: Extinction, Evolution or Revolution?

For some years now the general uptake of IPv6 has appeared to be "just around the corner". Yet the Internet industry has so far failed to pick up and run with this message, and it continues to be strongly reluctant to make any substantial widespread commitment to deploy IPv6. Some carriers are now making some initial moves in terms of migrating their internet infrastructure over to a dual protocol network, but for many others it's a case of still watching and waiting for what they think is the optimum time to make a move. So when should we be deploying IPv6 services? At what point will the business case for IPv6 have a positive bottom line? It's a tough question to answer, and while advice of "sometime, probably sooner than later" is certainly not wrong, it's also entirely unhelpful as well! more

The Politics of Email Authentication, 2006 Edition

A student at a well-known US university wrote me and asked whether, given the huge national interest in getting the industry to unite behind (at least) one format, did I think that the FTC should've played a stronger role in pushing the industry to adopt an authentication format? I said: Nope. Part of the reason it's taking so long to agree on a standard is that the process is infested with academic theoreticians who are more interested in arguing about hypotheticals and pushing their pet spam solutions than in doing something useful... more

What’s in a Name?

Internet domain names are truly bizarre. There is nothing especially remarkable about them from a technical perspective, but from a social and political perspective they are all sorts of fun. We can have arguments over control of the DNS root, arguments over whether names are property, arguments over innate rights to specific names, arguments over a registrar's right (or lack thereof) to exploit unregistered names for private gain, and many more arguments besides. In this article, I'd like to explore the argument-space rather than defend any particular position in it. In so doing, I hope to illuminate some novel (or under-emphasised) perspectives on the matter. more

She Gave Me a Fake Phone Number!

The Intellectual Property Constituency, meeting at the ICANN conference in Vancouver, was interested in increasing ICANN's budget not because they thought they deserved it, but because they wanted ICANN to actually enforce the rules on the books about fake registrations. Now there's some evidence about how prevalent that is. If there's any surprise here, it's that the numbers are so low. more
