Guess what? It's happening again. Except instead of the email using my real name, it's for my Tsaiko gmail account. I now have a reservation confirmation from Japan Airlines for a Japanese lady in my inbox. It's all in Japanese. There's another email associated with it that I could forward it to, but I don't speak Japanese. I don't know how to tell this lady that she had accidentally used my email address.
I just... I can't believe this is happening again. In the exact same way. The last multi-year email problem started with receiving a confirmation email from the airlines.
