This is true, but even Gmail has false positives. They just get a more
of a pass for it than the rest of us do. If they reject an email it's
the senders fault, if the rest of us do it's our fault.
One good method I've found to further reduce false positives is to audit
logs and limit the results to senders that only attempted to send mail
to 5 or less customers. Since the networks on here are almost entirely
spam and very little ham, you just need to expose the tiny minority that
might slip through the cracks. The ones that only tried to reach the
least number of customers are usually the most meaningful.

It's working. We've seen dramatic shifts in inbound spam that
attempts to compensate for it. We proactively mapped the valid
senders in networks that send more spam than ham. We're rapidly
processing whitelist reauests from customers to fill in the gaps,
and those requests have slowed to a crawl. We rejected over 80
million spam email this year using this strategy.
It works from your point of view (and your customers). I was writing
from
the point of view of people who cannot send mail to your customers
because
of excessive blocking.
Instead of going through the hoops of getting whitelisted, they would
probably just make a Gmail account and send from there, as it isn't
blocked.
Or move to a different form of communication than email. That may be
the
reason why whitelist requests "have slowed to a crawl".
And you won't see this in your spam stats.
