Actually, Yahoo have just implemented a new complaint feedback loop in the 
past few days. They ask for details of DomainKeys or DKIM, but don't seem 
to require either. Oh, actually, you can sign up without either DomainKeys 
or DKIM, but you only get feedback when they see a DK or DKIM signature.

Interestingly, you don't get feedback when Yahoo has put your mail into a 
spam mailbox. Only when it's marked as spam by the end user.
