Having those three records in place is considered the best practice. As the saying goes, “An ounce of prevention is worth a pound of cure.” For email, this has never been more true. Having all three records in place shows that your email domains are truly who they say they are. It also shows that you as an administrator, and your domain administrators as well, are all serious about ensuring you’re following best practices and doing your part to prevent spam, phishing, and other email security issues.
