Okay, Google's Spam filtering false positives are getting really annoying

For the past week or so, Gmail has gotten *very* aggressive about dumping email from Yahoo users that are going through certain mailing lists into the Spam bucket. I assume that there is some technical reason for this (most likely, they've gotten more rigid about some email-authentication protocol that isn't working well when passing through the mailing lists), but it's getting bloody damned annoying: it's up to half a dozen false positives a day, and no real Spam that I've seen. Indeed, they're not even claiming that it *is* Spam -- they're just dumping it into the Spam folder with a message saying "we can't authenticate this".

Does anybody know of a way that those of us who can tell the difference between a phishing scam and a real email can tell them, "Yes, I know, whatever, just freaking knock it off"?
