As unusual as it may be for a lawyer to speak at a IETF meeting, Ian Walden gave a lecture on Data Protection Directives and updates thereof. He said they affect some 90 jurisdictions. A difference between email addresses and cookies - the latter are the main subject of the January 2012 update of the directives - is that after more than a decade of enforcement, specific browser extensions may allow users to browse what cookies they have, while no record states whom they conferred their email addresses to. more
Return Path published their most recent Global Deliverability report this morning. It shows that inbox placement of mail has decreased 6% in the second half of 2011. This decrease is the largest decrease Return Path has seen in their years of doing this report... Filters are getting more sophisticated. This means they're not relying on simply IP reputation for inbox delivery any longer. more
A lot of people are fascinated by the news story that Anonymous managed to listen to a conference call between the FBI and Scotland Yard. Some of the interest is due to marvel that two such sophisticated organizations could be had, some is due to schadenfreude, and some is probably despair: if the bad guys can get at these folks, is anyone safe? more
A consortium of companies including Google, Microsoft, Facebook and Paypal have announced that they were collaborating and coming up with a new protocol known as DMARC -- the Domain-based Message Authentication, Reporting and Conformance. What is DMARC? more
In a presentation EU Commissioner Viviane Reding gave a preview of the new Privacy regulation her DG is preparing. As she states, privacy rules need to be brought up to date and harmonized. With all 27 member states having the same rules and tools to enforce, a company only will deal with one privacy commissioner... So, what if we, for the sake of this blog, take this initiative towards spam and cyber crime. What would this do to spam enforcement? more
For email usage, abuse reporting requires cooperation between senders and receivers. That's why RFC 5965 specified a standard format for it. However, Wikipedia lists only 18 feedback providers today. It is often said that the number of legitimate mailbox providers in the world is rather small, possibly some hundreds of thousands, but certainly more than that. more
Greylisting is a hoary technique for rejecting spam sent by botnets and other poorly written spamware. When a mail server receives an attempt to deliver mail from a hitherto unseen sending host IP address, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail software does try again, at which point you note that the host knows how to retry and you don't greylist mail from that IP again. more
It is with great sadness that we announce the passing of Jesse David (J.D.) Falk, a highly regarded and long time contributor to CircleID. more
Signing Email is now a Draft Standard! Signing email transitioned from a proposed standard to a draft standard (RFC6376 -- one of the new RFCs) over at the IETF a few days ago. The other is RFC6377. Let's go through a brief history of DKIM RFCs to refresh our memories... more
How large is your digital footprint? If you pulled together your email account, web site, blog, social networking accounts, and every other virtual identity you have online, just how well known are you on the Internet? Have you ever stopped to consider what happens to your online identity when you die? How would your online friends know? What would happen to your accounts and your content? more
I visited Judge Fogel's courtroom this morning to listen to the oral motions in the Holomaxx cases. This is a general impression, based on my notes. Nothing here is to be taken as direct quotes from any participant. Any errors are solely my own. With that disclaimer in mind, let's go. more
Last week, Synacor joined other major mailbox providers by introducing a complaint feedback loop service -- powered by ReturnPath. This increases the number of public complaint feedback loops available today across the internet. more
In our last installment we discussed MIME, Unicode and UTF-8, and IDNA, three things that have brought the Internet and e-mail out of the ASCII and English only era and closer to fully handling all languages. Today we'll look at the surprisingly difficult problems involved in fixing the last bit, internationalized e-mail addresses. more
Back when the Internet was young end servers came with shovels (for the coal), everyone on the net spoke English, and all the e-mail was in English. To represent text in a computer, each character needs to have a numeric code. The most common code set was (and is) ASCII, which is basically the codes used by the cheap, reliable Teletype printing terminals everyone used as their computer consoles. ASCII is a seven bit character code, code values 0 through 127, and it includes upper and lower case letters and a reasonable selection of punctuation adequate for written English. more
Gradually it seems the word is spreading about a new blocking methodology to interrupt the ability of end users to click and visit phishing sites - thereby having their personal information/credentials at risk. This is the DNS Response Policy Zones. DNS RPZs allows companies that run recursive resolvers to create a zone that will not resolve specific domains. more
