I "solved" this issue a long time ago by rejecting all mail to or from Yahoo. When they connect to my server they get a failure notice that I don't accept connections from a company that leeks 3 billion people's passwords. There's been no fallout from this at all, other than I know some people have abandoned yahoo.com because of it. I do not trust yahoo one bit, and I won't allow them on my network. Long before I decide to blacklist them, they were absolutely horrible anyway. A constant stream of spam and malware, no response to enquiries, and making persona mail from users in the yahoo serf's mailbox as spam for reasons no one could ever explain The only company nearly as bad was rr.com, whom I also blacklisted. periodically I check my logs to see what is going on and I am happy to report I see very few connections form Yahoo and, as I expect, they are all obvious spam. May not work for anyone else, but it works for my server. -- When you come to the fork in the road, take it
