None of this works:
1. Ensure the mail "connection" is signed in. It is. It's signed in just fine.
2. Ensure you're not "un-subscribed" from the emails. I am not. Nobody is. I re-signed up for fun. This isn't the problem.
3. Ensure your email is in the address list. My address is there. So are others. NONE of us get emails. This all happened without any actions from me.
4. Ensure the email isn't going to junk. As stated, this has been working great for a long time. It magically stopped all on its own.
