Which has done nothing but allow countless Exchange server to HELO with exchange.local and other such idiocy, not to mention contribute to the spam problem.RFC 1122 (Requirements for Internet Hosts - Communication Layers) section 1.2.2 (Robustness Principle): "Be liberal in what you accept, and conservative in what you send"
Every time you try to configure your server for strict parsing to help block spam, you get an email from some admin who doesn't know the first thing about SMTP but wants to know why you're blocking their email.
