Universal Acceptance of New Top-Level Domains Reloaded

One challenge for all new top-level domains (TLDs) is the so-called Universal Acceptance. Universal Acceptance is a phenomenon as old as TLDs exist and may strike at many occasions... The effect when universal acceptance hits you is that you cannot send or receive email, get error messages or even worse when it looks like everything works but it does not and you do not even get a notification. more

Addressing Search Engine, Website, and Provider Accountability for Illicit Online Drug Sales

Garth Bruen reports on a paper published by the American Society of Law, Medicine & Ethics of Boston University School of Law authored by Bryan A. Liang and Tim Mackey titled, "Searching for Safety: Addressing Search Engine, Website, and Provider Accountability for Illicit Online Drug Sales". From the paper: "Online sales of pharmaceuticals are a rapidly growing phenomenon. Yet despite the dangers of purchasing drugs over the Internet, sales continue to escalate. These dangers include patient harm from fake or tainted drugs, lack of clinical oversight, and financial loss. Patients, and in particular vulnerable groups such as seniors and minorities, purchase drugs online either naïvely or because they lack the ability to access medications from other sources due to price considerations. Unfortunately, high risk online drug sources dominate the Internet, and virtually no accountability exists to ensure safety of purchased products."  more

Spamhaus Policy Block List Update

Recently, I wrote about the Spamhaus Policy Block List (PBL), suggesting senders encourage their network/connectivity service providers (whomever they lease or purchase IP addresses from) to list their illegitimate email-sending IPs as a step towards improving the overall email stream on the internet. The initial PBL was seeded with listings from the Dynablock NJABL ("Not Just Another Bogus List"), which at the time of the cut-over was at more than 1.9 million entries... more

Soon in a Mail Box Near You: Internationalized Email Addresses

The EAI working group of the IETF has finished (part of) its work on the interationalization of email addresses. This, together with Internationalized Domain Names (IDN) will make it possible to send email messages to non-7 bit ASCII addresses... There are 3 RFCs, covering changes to the SMTP protocol, e-mail message format and delivery Status Notifications. more

Digging Through the Problem of IPv6 and Email - Part 3

One idea to make the problem of mail more manageable is to restrict the address space that is allowed to send mail. In an ideal world, we'd restrict where mail mail servers could send mail from. So, if we say that the number of individual mail servers in the world will probably never exceed 32 million (not unreasonable), or 2^25, then what if the 25 least significant bits were reserved for mail servers? more

Email Recommendation Engine for ESPs – Text Length Optimization (Part II)

Popular email editors today have no way to optimize for text length. An email marketer may attempt to build her content but has no idea whether that content is optimized related to word count for a specific industry/client. As it relates only to text length, does the email have too many or too few words. Currently, there is no built-in predictive model to inform her. Well, until now. Last month we described an evolutionary real-time data-driven process for email campaign builders to have at their disposal. more

Commentary on the FTC Spam Summit

The following speech was prepared with the intention of using portions of it during the FTC Spam Summit, but CAUCE was not given the opportunity to participate due to time constraints... "I am here today to question. Yesterday we heard how the tenor of the discussion about spam became more mature. How, in the period of time that has elapsed since the last summit, things have developed as an industry. That may be true, but I question if the discussion at hand here this week is truly a big tent effort. I see few anti-spammers here..." more

Searching for Truth in DKIM: Part 3 of 5

Last year, MAAWG published a white paper titled Trust in Email Begins with Authentication [PDF], which explains that authentication (DKIM) is “[a] safe means of identifying a participant-such as an author or an operator of an email service” while reputation is a “means of assessing their trustworthiness.”

Phishing Attacks Targeting Executives Now Top Cybersecurity Insurance Claims, Says AIG

Does the First Amendment Forbid Spam Filtering?

A friend of mine wrote to ask: "The Supreme Court overturned the Jaynes conviction on First Amendment grounds, yes? I'm wondering what that could mean from the spam filtering perspective." Spam filters, and in particular DNS blacklists are intended to prevent e-mail from being delivered. Doesn't the First Amendment make it illegal to block speech? The short answer is no, but of course it's slightly more complicated than that in practice. more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more
