Your "inner skeptic" is right, it's junk mail. Delete it. Don't waste your time sending it to eBay though. Even though they have a "trust and Safety" department, it's a waste. There is nothing they can do about it anyway.
If the message is real, it will also show up in the "My Messages" section of your My eBay page.
In time you'll become more able to recognize what's real, and what should be ignored. Right off the bat "e-bay" and "ebey" are dead giveaways.
