Hi
Posts can get trapped by the comment spam filtering especially when editing and reposting. The email notification is from the Community system not a real person. As the OCE's aren't back to release the post from comment spam until next week I've appended the original unedited notified version to your post.
As for whether your email has been compromised or spoofed here's the advice article:
Please do try the Reset your Password option to reset your password. Or you can change your email password in MyAccount if the email account is listed in your MyAccount. Here's the advice article on managing your email in MyAccount. As it's not the billing email address then the MyAccount login or the billing email address will not be affected.
