Articles I read today

It has been a rather busy day today, I do not have a full blog post. I did see a couple posts come across my RSS feeds. Both of them have content I want to talk about and discuss in a little more detail, as I think they touched on some very interesting issues.
Network World has an article interviewing Mark Risher from Yahoo. The article discusses Yahoo’s use of DomainKeys as part of their inbound mail filtering.
Mickey has an article about how to deal with ISPs when attempting to troubleshoot a blocking issue.
More details and commentary on both articles later this week.

Update on Yahoo and the PBL

Last week I requested details about Yahoo rejections for IPs pointing to the PBL when the IP was not on the PBL. A blog reader did provide me with extremely useful logs documenting the problem. Thank you!
Based on my examination of the logs, this appears to be a problem only on some of the Yahoo! MXs. In fact, in the logs I was sent, the email was rejected from 2 machines and then eventually accepted by a third.
I have forwarded those logs onto Yahoo who are looking into the issue. I have also talked with one of the Spamhaus volunteers and Spamhaus is aware of the issue as well.
The right people are looking at the issue and Spamhaus and Yahoo are both working on fixing this.
Thanks for the reports and for the logs.

Blogroll

I added a few blogs to my blogroll today.
Terry Zink works at Microsoft handling spam blocking issues for one of their platforms. His posts offer insight into how recipient administrators view spam filtering. He has a long, information dense series of posts on email authentication.
E-mail, tech policy, and more is written by John Levine, a general expert on almost everything internet, especially spam and abuse issues. He posts somewhat irregularly about interesting things he sees and hears about spam, abuse, internet law and other things.
Justin Mason’s blog contains information from the primary SpamAssassin developer. Like Terry’s blog, it gives readers some insight into the thought process of people creating filters.
Al Iverson’s blogs have been on my blogroll for a while now. His DNSBL resource contains information about various DNSBL and how they work against a single, well defined mail stream. His spam resource blog provides information about delivery and email marketing from someone who has been in the industry as long as I have.
Email Karma is Matt Verhout’s blog and contains a lot of useful delivery information.
