Fine Grained Mail Filtering With IPv6

One of the hottest topics in the email biz these days (insofar as any topic is hot) is how we will deal with mail on IPv6 networks. On existing IPv4 networks, one of the most effective anti-spam techniques is DNSBLs, blackists (or blocklists) that list IP addresses that send only or mostly spam, or whose owners have stated that they shouldn't be sending mail at all. DNSBLs are among the cheapest of anti-spam techniques since they can be applied to incoming mail connections without having to receive or filter spam. more

The Naive Arrogance of FUSSPs

Everyone who's been in the e-mail biz long enough knows the term FUSSP, Final Ultimate Solution to the Spam Problem, as described in a checklist from Vern Schryver and a form response that's been floating around the net for a decade. FUSSPs fall into two general categories, bad ideas that won't go away, and reasonable ideas that are oversold. more

Spam Arrest’s Sender Agreement Fails Because Email Marketer’s Employees Lacked Authority

People hate receiving spam, but most people stopped obsessing about spam a decade ago or more. In the interim, anti-spam filters have improved dramatically. Still, some anti-spammers hate spam so passionately -- or, perhaps, hope to put a little coin in their pockets -- that we still see a steady stream of lawsuits against email marketers. For the most part, those lawsuits don't win; in the past half-decade, repeat anti-spam plaintiffs have rarely won in court. more

How Not to Stop Spammers

Spam Arrest is a company that sells an anti-spam service. They attempted to sue some spammers and, as has been widely reported, lost badly. This case emphasizes three points that litigious antispammers seem not to grasp: Under CAN SPAM, a lot of spam is legal; Judges hate plaintiffs who try to be too clever, and hate sloppy preparation even more; Never, ever, file a spam suit in Seattle. more

The Death of IP Based Reputation

Back in the dark ages of email delivery the only thing that really mattered to get your email into the inbox was having a good IP reputation. If your IP sent good mail most of the time, then that mail got into the inbox and all was well with the world. All that mattered was that good IP reputation. Even better for the people who wanted to game the system and get their spam into the inbox, there were many ways to get around IP reputation. more

CAN SPAM Issues in Zoobuh V. Better Broadcasting

Last week a Utah court issued a default judgement under CAN SPAM in Zoobuh vs. Better Broadcasting et al. I think the court's opinion is pretty good, even though some observers such as very perceptive Venkat Balasubramani have reservations. The main issues were whether Zoobuh had standing to sue, whether the defendants domain names were obtained fraudulently, and whether the opt-out notice in the spam was adequate. more
