Some of us do not have the luxury of acting even the slightest little
bit of a BOFH.

I see more spam[1] from any one of Hotmail, Yahoo, or GMail than I do
coming through the whole set of email service providers I've IDed
(both email-hosting and bulkmailers) of all stripes.

As an ISP mail admin, I **CANNOT** afford to block legitimate mail
from any source, and if I see a report that a legitimate mail was
blocked by any local rules or DNSBL data, I change the local rule or
delete the offending local DNSBL entry ASAP.

[1]  At least, so far as "messages reported as missed spam by
customers".  I don't keep watch on the stuff that gets tagged.
