SpamCop and false positives from Yahoo
I'm seeing a lot of false positives from SpamCop blacklisting Yahoo mail
IP's.
For example:
http://www.senderbase.org/senderbase_queries/detailip?search_string=98.138.82.0%2F24
http://www.senderbase.org/senderbase_queries/detailip?search_string=115.178.12.0%2F24
Anyone tried or anyone have a contact at SpamCop who can get Yahoo mail
blocks whitelisted?

Yahoo sometimes selects specific IP ranges for sending mail with
spammy-looking qualities so as to keep their less spammy users on
cleaner relays. This is mostly damage control and is by no means
reliable. It certainly can't have trust extended to third-party indices
like CBL, SpamCop, or DNSWL, though (as you can see) it does leave a mark.
Note, I am not speaking for my employer, etc etc. (Please assume this
unless I say otherwise.)

White listing yahoo is a horrible idea. As usual, you should just use
spamcop for scoring, not outright blocking email. Spamcop has had a poor
reputation for false positives for a quite awhile now.

Excuse the top post, on a blackberry.
They have a list/newsgroup where you can email the 'deputies'. If it is still the way they used to be run, they aren't really false positives. Those servers really are sending spam. I think all listings are automatically removed after a few days or so.
