CAMBRIDGE, MA --- The MIT Spam Conference is under way.
Most of the presentations follow the content filtering
school of thought. I, personally, feel that content
filtering has reached the point of diminishing returns.
Sender authentication, which SPF pioneered, allows us to
ask a different question: "are you a stranger?"
We already know that addressbooks are only the most obvious
way to answer that question. Social networking offers a
richer answer: if you're three degrees of separation away
from me, that's probably good enough.
P. Oscar Boykin today announced some interesting results in
this space. It was previously covered on Slashdot:
