Engineers in the Internet Engineering Task Force, in the Messaging Anti-Abuse Working Group, and elsewhere have been debating how to handle e-mail-server blocklists in an IPv6 network. Let's take a look at the problem here. We basically have three ways to address spam, in our goal of reducing the amount of spam in our inboxes... more
The Anti-Spam Research Group (ASRG) published a draft for an Overview of Email DNSBL Best Practices. We can take a step back and review paragraph 2.2.5 (Conflict of Interest)... Some DNSBLs used for blocking/negative reputation have had a practice of requiring fees or donations to charities from the listee for delisting. It is generally considered entirely appropriate for a DNSBL to charge for access to it by its users -- the definition of a commercial DNSBL. more
It's easy to look at Amazon SES and sigh. Thousands of low-end customers sending mail from a shared IP pool? Amazon already knows that trick never works! Just one spammer will ruin the reputation of those IP addresses, resulting in ongoing delivery problems for everyone who uses the service. It is possible that Amazon can build the systems and human processes to keep spammers out; certainly sounds like they want to. more
The gathering of coherent data on cybercrime is a problem most countries haven't found a solution for. So far. In 2011 it is a well known fact that spam, cybercrime and botnets are all interrelated. The French database Signal Spam may be a significant part of the solution to gather, analyse and distribute data on spam, phishing, cybercrimes and botnets, but also be a forum in which commercial mass e-mail senders and ISPs can work on trust. more
Anyone who has been watching the technology industry for more than a couple of years quickly learns to recognize FUD: Fear, Uncertainty and Doubt. FUD is (apparently) widely believed to be an effective marketing technique, especially when it comes to security, privacy, or scarcity. But the FUD often falls flat. Scarcity, in particular, is rare on the internet -- even rarer than privacy or security. There's constant FUD about scarcity of bandwidth, but the pipes get upgraded. Attempts to impose artificial scarcity through paywalls or other devices inevitably fail in the face of free alternatives. Even the scarcity of IPv4 addresses, which have indeed run out at the top, hasn't affected end users at the bottom yet -- and probably won't, for a long time. more
Yesterday Goodmail sent out mail to all their customers announcing they are ceasing operations and taking all their token generators offline as of 5pm pacific on February 8th. While this is a bit of a surprise on one level, I'm not that shocked. Ken Magill mentioned in August that Goodmail was on the sales block and rumors have been circulating for weeks about significant changes coming to Goodmail. ... Despite the free service, people at some of those ESPs told me they were having difficulty getting customers to adopt Goodmail. more
Spear phishing is the unholy love child of email spam and social engineering. It refers to when a message is specifically crafted, using either public or previously stolen information, to fool the recipient into believing that it's legitimate. This personalization is usually fairly general, like mentioning the recipient's employer (easily gleaned from their domain name.) Sometimes they address you by name. Much scarier is when they use more deeply personal information stolen from one of your contacts... more

The New York Times recently posted an article about how email is getting a makeover and how the communication medium is being shunned by the younger crowd as they move more and more towards other platforms. If you like using email, that means you're an old fogey. When the Internet exploded in growth in 1995, email was a pretty cool commodity. Now, it's not that big a deal anymore, according to the New York Times. more
A couple things related to the intersection of email and law happened recently. The 6th circuit court ruled that the government must have a search warrant before accessing email. The published opinion is interesting reading, not just because of the courts ruling on the law but also because of the defendant. more
