Hacker News story: Yahoo is sending email from no-reply@cc.yahoo-inc.com

Yahoo is sending email from no-reply@cc.yahoo-inc.com
I just received an Unexpected sign-in attempt email from yahoo. The from address is no-reply@cc.yahoo-inc.com. I was sure this was a phishing email. But this is the from address yahoo chooses to use for official account related emails. This seems like a really poor choice for people trying to determine if emails are from the actual company. Anyone have any thoughts or insight on this? Why not use no-reply@cc.yahoo.com or even no-reply@yahoo.com so it's more clear it's from Yahoo. 0 comments on Hacker News.
