Why Blog?

There was a good piece in the New York Times yesterday about blogging, including some good quotes from Jarvis. I’m getting the hang of it, but I have to say that blogging in the bathroom is taking things a little bit too far.

SPF and Caller ID for Email Merge – What Does This Mean?

Yesterday’s announcement that Microsoft is going to merge its nascent Caller ID for Email authentication standard with the more populist Sender Policy Framework (SPF) is an interesting development in the war on spam. But what does it really mean? It means that sender authentication is headed towards a standard. Where once there were three, now there are two (Yahoo Domain Keys is another standard, although it’s still a little unclear whether it’s competitive or complementary).

Popular Misconceptions About Bonded Sender

There have been many postings about Microsoft’s recent announcement to use Ironport’s Bonded Sender Program as one of its many tools to fight spam and reduce false positives.

Periodically, I’ve even pondered whether or not they violate someone’s first amendment rights. It’s maddening to know you’re a good guy in the email world, you can get put on a blacklist because some anti-spam zealot decides he or she doesn’t like you on a whim, you can’t complain or get off of the list, you may not even know you’re on the list, then you’re downloaded thousands of times by naively trusting or equally zealous sysadmins, and boom — your emails aren’t getting through any more. Then yesterday, I was looking at…
