Gordon v. Virtumundo, the sequel

I was slightly surprised that Gordon was still pressing on with his case against Virtumundo. It seems that Mr. Gordon appealed, again, to the 9th circuit. James Samuel Gordon, Jr., appeals pro se from the district court’s summary judgment in his action alleging that defendant’s transmission of unsolicited commercial email or spam violated federal and […]

About that Junk Folder

I use a pretty standard mail filtering setup – a fairly vanilla SpamAssassin setup on the front end, combined with naive bayesian content filters in my mail client. So I don’t reject any mail, it just ends up in one of my inboxes or a junk folder. And I have a mix of normal consumer […]

Opt-in vs. opt-out

Jeanne has a great post up at ClickZ comparing the performance of mail to an opt-in list to performance of mail to an opt-out list. The article looks at opens, clicks and click through rates over 7 quarters (Q1 – Q4 2010; Q1 – Q3 2011) covering 330 million emails. I strongly suggest anyone interested […]

Listen to me talk about filtering, blocklists and delivery

I did an interview with Practical eCommerce a few weeks ago. The podcast and transcript are now available. I want to thank Kerry and the rest of the staff there for the opportunity to talk email and filtering with their readers. Happy Thanksgiving everyone in the US.

We lie more in email than in person

People are more prone to lie over email than face to face.

Having the same conversation

This morning I was reading a blog post about the failure of the congressional super committee. The author commented parties can’t reach an agreement if they’re not even having the same conversation. I realized this is just as true in email as it is in politics. All too often we’re not having the same conversation. […]

More legal problems for Boris

Boris Mizhen is once again on the wrong side of legal action. This time it’s not as simple as Microsoft suing him for creating hundreds of thousands of accounts to try and game the spam scoring system. Instead, he seems to have run afoul of the FTC. This case isn’t obviously about email, but the […]

Email lost a mighty advocate

Last night J.D. Falk passed away from stomach cancer. For those of us who were privileged to know him, it was not unexpected but it is still a sad day. CircleID has a memorial post up. I’ve known of JD since I started in email in the late ’90s. I had the privilege of meeting […]

IP reputation and the bulk folder

I’ve spent much of today talking to various people about IP reputation and bulk foldering. It’s an interesting topic, and one that has changed quite a bit in the past few months. Here are a few of the things I said on the topic. Generally IPs that the ISP has not seen traffic from before […]

Vetting customers

MAAWG has published a BCP for vetting new customers. This is the culmination of much work by a lot of people. One of the best things about the document is the discussion of how spammers attempt to hide their identity. All too often I’ve been called in by ESPs to help them identify how a […]

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment


  • Fixing discussion lists to work with new Yahoo policy

    Al has some really good advice on how to fix discussion lists to work with the new Yahoo policy. One thing I would add is the suggestion to actually check dmarc records before assuming policy. This will not only mean you're not having to rewrite things that don't need to be rewritten, but it will also mean you won't be caught flat footed if (when?) other free mail providers start publishing p=reject.No Comments
