Well for me it was more the situation that some of the DNSBL get a bit
*too* aggressive, when you look at their "mission statement" it's more a
hate statement (SpamCop excluded).

I was recently using blackholes.easynet.nl but heard that they block whole
netblocks which have just one spammer in the netblock. Philosophically I
can't agree with that, and practically I am not going to block mail from an
innocent company just because some ratbag is spamming from the same
netblock and the ISP is not moving fast enough to suit some black list
maintainer with a "manifesto".

For example we got put on SpamCop because some reseller of our products
(who had **requested** to go on a closed mailing list) got annoyed with a
mailout and instead of clicking "Unsubscribe" or calling us on the phone
(he had the number) and saying "take me off" 'reported' us to SpamCop. Boom
no recourse, no notification from SpamCop to confirm - we're just
blacklisted. Trial without jury. That's why I don't use SpamCop.

We traced it back through logs and gave the reseller a piece of our mind,
but that does not help getting yourself (quickly) off a blacklist like
SpamCop.

For a corporate environment I prefer lists which are _factual_ - you either
are a *verifiable* open proxy or not, an open relay or not, dial up user or
not etc.
