Four large Internet service providers agreed yesterday to a
partial truce in their battle with one another over
potential technology to stop junk e-mail in hopes that they
can devote their united energy to fighting spam.
1. Several of those providers are primary sources of spam (and spam
support, including web site hosting, mailing list services, mailboxes,
etc.). Perhaps they should clean up their own networks before
attempting
to mount the soapbox and tell the rest of the world what to do.
Do we have any hard statistics on this? I work for one of the above
and we fight internal spam hard. Of course to be fair, we would need
to get the results normalized by the subscriber base.
I keep hearing about how several of the above are primary sources,
but rigorous data are hard to come by.
For some numbers, please see the presentation by Carl Hutzler, director
of anti-spam at AOL, given at NANOG in chicago a some months ago.

2. SPF/domainkeys/et.al. are moot. Spammers have already developed a
number of methods to work around them, and the only reason we haven't
seen
these on a large scale (to date) is that there simply hasn't been any
need
for spammers to deploy them. Note as well that SPF/domainkeys et.al.
only
deal with SMTP spam -- thus severely limiting their applicability.
3. The proposals about rate-limiting demonstrate just how amazingly
out-of-touch these people are with current spammer strategies and
tactics.
Implementation of these would do NOTHING to stop spam, while having a
devastating effect on legitimate mailing lists -- which are some of the
Internet's most valuable resources.
