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.

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.
