Received this email, is it legitimate?

No. Forward it to reportphishing@apple.com as an attachment and then delete it.

A legitimate Apple email won't have anything after the apple.com in the sender's address.

It's a scam, forward to Apple here: Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support
