Re: Fw: Webcast Today: Protect you organization against next-gen spammers

Boy, this presentation was incredibly biased.  IMHO, I think having a central
solution like Postini has a lot of downsides which weren't mentioned.  For
example, there was no mention of where their "data centers" were located and
whether they are physically vulnerable (earthquake, etc.).  Also, whether, if a
particular hole is discovered in the infrastructure, some set of people could
quickly take advantage of that before the hole is plugged up.

Their broader ideas are very good, 'though -- I just don't like the
implementation.  The idea of having access to information of a number of
spam-fighters can be really useful.  I just personally like the peer-to-peer
model (such as Cloudmark) better because it's more robust and more
customizeable.  (I think Cloudmark's implementation needs some work, too,
'though.)

It seems like the domains-oriented service that Postini offers is so low-cost
that they will probably be the long-term winners of this.  OTOH, once a SPF or
Domain Keys solution is implemented, such services will gradually become less
desired and other home-grown solutions (probably peer-to-peer or RBL-oriented)
will sprout.
