The "postfix" mailer has an option to refuse such E-mail. If this is 
100% true for you, you can use that option. From my experience, this is 
not true at all. Many, many companies, even big companies, have mistakes 
in their DNS setup. I agree that this would be a very good thing to 
enforce, but personnally I wouldn't like to be responsible if one of 
these big companies could not reach the sales people at the place where 
I work! If it would be globally enforced, I'd join.
