Earlier this week DirectMag published an article talking about RoadRunner blocking images by default. I did talk to someone over at RoadRunner and found out a few more details about this change. What is happening is that RR is rolling out a new web interface. This interface has both a bulk/spam filter and has images […]
Yahoo is aware of the recent problems and have been working feverishly to fix them. A Yahoo employee posted to a mailing list earlier today, explaining some of the recent issues. The summary is: 1) The Yahoo delays are a result of a tighter spam filtering policy. The delays are the result of the system […]

There comes an inevitable point in some of my longer term consulting gigs where my client asks me some version of the following question: I still get spam in my inbox, so why is the email I send blocked? So what is your best answer?
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 […]

This morning I received an email from AOL detailing what happened as relayed by the ESP. IronPort Open Relay Vulnerability Systems Affected IronPort A60 running software version 2.5.4-005. […]
