Today I got a phishing scam email for Amazon. The target domain was hosted on Yahoo! The WHOIS info showed the tech contact as domain.tech@YAHOO-INC.COM, so that's one of the places I sent the email (as well as abuse@). So, YAHOO-INC.COM rejects the email because clamav detected a phishing scam in the email. Um.. no shit!

You cannot report the scam because the email containing the scam will be filtered because it contains a scam. Hopefully, abuse@ for yahoo and Amazon get it, and probably the many others reporting the same one.
