Absolutely it's a scam. Do not respond to it in any way - they are trying to snaffle your login details.
Apple will always address you by name, not your email address: they will never send you an email like this - if the do have to lock your ID for security reasons they won't tell you, they will wait for you to find out and contact them.
It's a bad idea to post your email address, even in an image, and I've asked the Hosts to remove it. If you need to post an image like this in the future it's advisable to block out your address.
