We currently run our hosted systems requiring reverse DNS and haven't really had any complaints about mail not being received. While there's no rule requiring reverse DNS, systems without it are much more likely to be spam originators in my experience with our system. The few systems I've come across that legitimately send mail but had broken reverse DNS were more than happy, and able, to fix it quickly and understood immediately the point of rejecting connections on such a condition.

Agreed. There is no rule that demands reverse DNS. It's a nicety and that's
