Is [email protected] a legitimate Apple email address?

Yes, that is a legitimate address.

The controversy only arises because sender email addresses can be easily spoofed so you could see an email with that address that is not from Apple. That is true for any email you receive. You would actually have to inspect the Email Headers to validate where it originates. When evaluating whether any email is a phishing email you NEVER rely solely on the sending address and have to ask yourself:

• Are they asking for my Password or linking to a site where that is asked.
• Are they asking for any financial info or linking to site where that is asked.

If the answer is Yes to any of those, then it is prudent to contact that company directly and for Apple that is done with the link below. Otherwise you treat the email as information only and if you have questions about that information then you would also contact the company directly.

Is this email legitimate? 

If you receive an email about an App Store or iTunes Store purchase, and you’re not sure whether it is real, you can look for a couple of things that can help confirm that the message is from Apple.

Genuine purchase receipts — from purchases in the App Store, iTunes Store, iBooks Store, or Apple Music — include your current billing address, which scammers are unlikely to have. You can also review your App Store, iTunes Store, iBooks Store, or Apple Music purchase history.

Emails about your App Store, iTunes Store, iBooks Store, or Apple Music purchases will never ask you to provide this information over email:

• Social Security Number
• Mother's maiden name
• Full credit card number
• Credit card CCV code

My receipts from Apple are being sent form this address.

What controversy? I have emails from no_reply.
