  Exactly.  Even for your own double opt-in customers, a percentage of
your messages are viewed as spam.  This means you are a spammer, at
least so far as they're concerned.  This isn't necessarily a bad
thing, as it shows us what we've been missing in the design of most
anti-spam systems.

  Any anti-spam system that lists you as a spammer because of such
customer reports, and refuses to allow you to participate in it
because of that label, is WRONG.  It's design is wrong, it's
implementation is wrong, and it's intent is wrong.  Such a system
cannot be trusted.  Witness the cross-listing of blacklists, due to
political weener-size arguments.  Those blacklists lost HUGE
credibility when they listed people that most did not view as
spammers.

  If we are to win the war against spam, we must co-opt the spammers.

  To put it another way, if we DON'T include the spammers in a system,
they *you* won't be included, either, because of your customers
issues.  I don't think you would like that.
