Let’s Talk: Reputation

The next 3 or 4 Let’s Talk sessions are going to be all about reputation. We’ll start with a general overview of reputation and identity, then move on to specific kinds of reputation (IP, domain, URL, content), then we’ll talk about how to create, maintain and repair reputation. Still working on the outline, but I’m pretty convinced this will be at least 3 sessions.

Let’s Talk Reputation: July 15, July 29 and August 12. 4pm GMT, noon eastern, 9am pacific.

As everything is taking longer the days, the signup page still isn’t finished. We’re still doing this manually so send me an email to laura-ddiscuss at the obvious domain and I’ll get you an invite.

Invites go out the Monday before the call.

Filtering by gestalt

One of those $5.00 words I learned in the lab was gestalt. We were studying fetal alcohol syndrome (FAS) and, at the time, there were no consistent measurements or numbers that would drive a diagnosis of FAS. Diagnosis was by gestalt – that is by the patient looking like someone who had FAS.
It’s a funny word to say, it’s a funny word to hear. But it’s a useful term to describe the future of spam filtering. And I think we need to get used to thinking about filtering acting on more than just the individual parts of an email.

Filtering is not just IP reputation or domain reputation. It’s about the whole message. It’s mail from this IP with this authentication containing these URLs.  Earlier this year, I wrote an article about Gmail filtering. The quote demonstrates the sum of the parts, but I didn’t really call it out at the time.
