I'm not really sure how email routing works, but someone ordered something on Amazon and I received the email instead of them. Or maybe we both got it, I don't know. The order doesn't show up in my account, so I'm certain I wasn't charged for it, but I shouldn't be getting other peoples' emails.
We'll say that my email is firstname.lastname@example.org, and somebody who's email is email@example.com places an order on Amazon. The confirmation email is sent to me at firstname.lastname@example.org. I checked the email header, and it did say To: email@example.com which is not my email address.
At first I thought that Google ignores periods in email addresses, but I tested the account setup and it doesn't give any error when you put a period in the address. I didn't create the account; I just used the "check availability" function and the address I chose with a period was fine.
Maybe someone with knowledge about how Email works could tell me why this happened. Is this a bug in the way Amazon sends emails? Or is it a bug in how Google receives them? Who should I report this issue to?
