I realize yahoo wants to protect us from spam/spoofed emails and requires DKIM (or maybe DMARC?). But sometimes we are trying to converse with a user we can't control. I recently needed a response from the California Franchise Tax Board (ftb.ca.gov) and never received it. It would be very powerful if users could whitelist various sources and control it as needed. For example, I might whitelist *.gov but if I found spam then I might delete it, or replace it with *.ca.gov (so I could get DMV, too). Or I might only temporarily whitelist only when I'm trying to converse with a particular site.

Hi Kenneth, thank you for the suggestion/request! And providing a user case for this, super helpful. Some nice changes coming to Yahoo Desktop and we will definitely share this with the right team. Thanks again!
