Why DomainKeys is Broken

The recent testing by Gmail of DomainKeys affords an opportunity to look again at what the impact of it may be in any attempt to introduce a Domino addin to verify DomainKeys signatures. I have here a sample of an email sent from Gmail and that same email after being delivered to the in-box of a Notes/Domino user who prefers MIME. There are differences which make DomainKeys a real problem at Domino shops (and, I suspect, others). more

Can TCP/IP Survive?

The following article is an excerpt from the recently released Internet Analysis Report 2004 - Protocols and Governance. Full details of the argument for protocol reform can be found at 'Internet Mark 2 Project' website, where a copy of the Executive Summary can be downloaded free of charge. ..."In releasing this section for comment, I would like to point out that the report's conclusions are based on a cumulative examination of various protocols and systems. We are at a point of time where other protocols and systems are equally problematic -- the report points to some significant problems with DNS structure and scalability, and also points out that, to all intents and purposes, the basic email protocol, SMTP, is broken and needs immediate replacement." more

The Rumors of Sender ID's Demise Are Exaggerated

While several news stories are reporting that Sender-ID has been killed, that is not entirely true. While Sender-ID in its current form is dead because of Purported Responsible Address (PRA), the compromise version with MAILFROM and PRA scopes is not. Also, the co-chairs want to stay away from any other alternative algorithms that do RFC2822 checking because of possible Intellectual Property Rights (IPR) claims by Microsoft on that as well. Andrew Newton, one of two co-chairs of the working group, wrote in an email today to the group's discussion forum... more

Sender Address Verification: Solving the Spam Crisis

There are many companies in the spam-fighting business and most, if not all, claim to be hugely successful. Yet spam is exponentially more prevalent today than it was just 2 years ago. How can one conclude that today's anti spam solutions are working? This year spammers will use machine-generated programs to send trillions of unsolicited email. Thankfully, a new anti-spam technology has made its way into the market. more

An Interview with the Lead Developer of SPF - Part II

CircleID recently interviewed Meng Weng Wong, the lead developer of Sender Policy Framework (SPF) and founder of Pobox.com. As one of the leading anti spam authentication schemes, SPF is used by companies such as AOL, Earthlink, SAP and supported by anti spam companies such as Sophos, Symantec, Brightmail, IronPort, Ciphertrust, MailArmory, MailFrontier, Roaring Penguin Software, and Communigate Pro. Last month, Microsoft announced its agreement to merge Caller ID, its own proposed anti spam authentication scheme, with SPF -- the joint standard is called 'Sender ID'. In this two-part interview, Meng Wong explains how SPF got started, where it is today and what could be expected in the future of email. more

Email Address Forgery

In my roles as postmaster at CAUCE (the Coalition Against Unsolicited Commercial E-mail) and abuse.net, I get a lot of baffled and outraged mail from people who have discovered that someone is sending out spam, often pornographic spam, with their return address on the From: line. "How can they do that? How do I make them stop?'' The short answers are "easily'' and "it's nearly impossible.'' more

80% of Spam Originating from Home PCs

The majority of spam -- as much as 80 per cent of all unsolicited marketing messages sent -- now emanates from residential ISP networks and home user PCs. This is due to the proliferation of spam trojans, bits of surreptitious malware code embedded in residential subscriber PCs by worms and spyware programs. Worm attacks are growing in frequency because they provide a fast means of infecting a vast number of computers with spam trojans in a very short period of time. It's no surprise that many service providers report an upsurge in spam traffic immediately following a worm attack. more

Can Technology Can Spam?

It seems to be impossible to implement a law against spam - unsolicited bulk email - without making a hash of it. At best, anti-spam laws are ineffective; at worst, they cause more problems than spam itself. Can technology fare any better? ...But despite this flurry of initiatives, we are yet to see a definitive answer to the spam problem. An Anti-Spam Technical Alliance has been formed by Microsoft, America Online, Yahoo! and EarthLink, but these companies continue to proffer competing solutions. Meanwhile, the technology being deployed in the spam wars is causing collateral damage, in the form of 'false positives' - email that is incorrectly categorised as spam, and so never reaches its intended recipient. more

Email, Privacy, and Engagement

After they finished the tenth installment of their enormous multi-volume history, The Story of Civilization, Will and Ariel Durant wrote a set of thirteen essays entitled The Lessons of History. I happened to pick up this volume yesterday; it's both slim and sweeping. The Durants loved history, and wanted to show their readership what waves and tensions and trends they perceived. It's not a great book, but it's an undeniably forceful one. One essay discusses the essential moral characteristics of individuals, listing six traits and providing "positive" and "negative" descriptions of ways in which people act. more
