Creative HTML Table Abuse

There’s an old-school ’90s HTML design trick that dates back to the dim and distant past before we had decent layout control in CSS. That’s “slicing” – chopping a large image up into multiple parts, then reassembling them in an HTML table. If you slice your images in an email and the end user hasn’t […]

Who are Rpost? Rpost are an email service provider of sorts. You may not have heard of them, as they focus on a fairly niche market – electronic contract and document delivery. Their main services are “Registered Email” – which provides the sender of the message with proof that the recipient has read the message, […]

Spamhaus dDOS

I got mail late last night from one of the Spamhaus peeps telling me that they were under a distributed Denial of Service (dDOS) attack. This is affecting email. Incoming email is delayed and they’re having difficulty sending outgoing email. This is affecting their responses to delisting queries. They are working on mitigation and hopefully […]

Broken record…

The Return Path In the Know blog listed 4 reasons mailing those old addresses is a bad idea. Ashley, the author, is completely right and I endorse everything she said. (Although I’d really like to hear what happened to the customer that added back all those addresses. What was the effect on that campaign and […]

Metrics, metrics, metrics

I’ve been sitting on this one for about a week, after the folks over at IBM/Pivotal Veracity called me to tell me about this. But now their post is out, so I can share. There are ISPs providing real metrics to senders: QQ and Mail.ru. Check out Laura Villevieille’s blog post for the full details.

AOL bounces and false positives

A number of people have been seeing an increase in AOL bounces over the last few days. Some of these are the new rejection 554/421 CON:B1 message. This is, basically, you’ve topped our thresholds, back off. The other one is a bit more interesting. The error message a lot of people are seeing is 554/421 […]

Do you have child subscribers?

Al has a short, but informative, post up on Spam Resource about privacy groups filing complaints with the FTC about companies violating the Children’s Online Privacy Protection Act (COPPA). Companies who are alleged to have violated COPPA include Nickelodeon, McDonalds and General Mills. The underlying issue appears to be the presence of “send to a […]

Emails that make you smile

This summer’s non-work project for me has been training for a 5K run with Fleet Feet in Menlo Park. As part of the training programs we get weekly emails from the store on Monday. As I was reading through today’s email, I found myself smiling and happy. Lisa, who is one of the store owners […]

  • AOL compromise

    Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something. Details are hazy, but there seems to be quite a bit of noise surrounding this incident. AOL hasn't provided any information as of yet as to what is going on.4 Comments

  • 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
