When systems disagree

A co-worker recently brought to my attention an interesting problem which involves differing ideas concerning precedence between RFC5321 and RFC3463. The result of the issue is that mail systems may experience unneeded delay in delivering mail. What’s going on? Gmail is returning the following error for over quota accounts: “452 4.2.2 The email account that you tried… Read More

Did you catch the death of Postini?

According to Google, all mail stopped flowing through Postini servers on June 15. Any Postini clients who had not made the transition by the end of May were supposed to have been forcibly transitioned then. Postini was a traditional troublespot when it came to deliverability. That shouldn’t be the case anymore. BibliographyPostini Transition to Google Apps,… Read More

What happened to Compu-Finder?

The Canadian Radio-television and Telecommunications Commission announced today that they have issued their first penalty against someone for sending email in violation of Canada’s anti-spam law. The penalty is substantial (C$1.1 million, or roughly US$881,700 at today’s exchange rate), but isn’t anywhere near the C$40 million potential maximum penality. Still, the size of the penalty is… Read More

“Nomenclatura” is a Latin word which refers to the “assigning of names to things.” It’s something that we often overlook, but is very important. The names that we assign to things tell us something about those things and sometimes will also tell us something about ourselves. I’m one of the first people to kind of blow… Read More

Domain Reputation

The Spamhaus DBL Team is making some change to their Domain Block List. The new changes will seek to emphasize domains associated with malware and bots, and allow administrators to more easily filter out entries related to legitimate URL shortening services. If you use the DBL, you should go have a look. If you don’t,… Read More

BT Transitioning Away From Yahoo! Mail

British Telecom (BT) announced last year that they would be transitioning away from Yahoo! Mail’s service for their customers after a decade. The concern at the time was over account security. Many BT customers were reporting that they were losing control of the mail accounts being hosted on Yahoo! Mail’s service. Now, the time for that transition has… Read More

Proper Assumptions

I’m at the Messaging, Malware, & Mobile Anti-Abuse Working Group meeting this week. After all of the sessions on Tuesday were over, I was speaking with a colleague from another company about how I handle some aspects of providing client advice and he suggested that I write that down in a blog post. When dealing… Read More

If ESPs were like ISPs…

Everyone wants to protect users and trap data. As a result, people like to send redacted complaints to email service providers (ESPs). Generally, I’m pretty happy to work with redacted data. I need to be able to tell which client sent mail. I need to be able to tell when they sent the mail (the… Read More

“Forward to a Friend” and Germany

Lots of folks have been talking recently about a September German Federal Court ruling[1] that “emails sent using a ‘send to a friend’ function are to be considered spam, unless the recipient had given prior express consent.” This is a fairly significant development in law. As a general rule, people advise that using a “Forward… Read More
