I've been seeing the same thing for years.  One of the domains I admin
gets about 5,000 pieces of mail a day for a 7-man shop.  Of those, less
than 200 a day are real mail.  The rest are spam.

Some blacklists work, SpamCop for one.  Very few false positives.  I
reject about 90% of all mail using that and other lists (not SORBS).

Interesting.  Are they trying out SPF to see if it will work?  One of
its major failures is in the situation you describe.

SORBS has always been overly aggressive and horribly slow to respond.

Unless you're emailing a newsletter or other bulk mail, they should not
be that much of a problem.  Bulk mail senders have some real problems.

Bottom line is that if we don't watch it, we'll end up losing control of
the net to proprietary interests, i.e. Microsoft.  I seem to recall
seeing that they were working on a separate email transport not based on
SMTP.  All that needs to happen is for that to become a de facto
standard that has royalties and we're all screwed.

One real problem is that there are literally millions of mail servers
out there.  Cutover would take years and would have to be staged.

Another problem is anonymity.  If I want to send anonymous email now,
its possible.  A system that is capable of keeping out spammers would
likely not allow anonymity, and that's a necessity.
