Reverse DNS basically looks up the PTR record for an IP address. Without dedicated IP's there may be confusion.
Only with broken software. :)
Well, we know there's no of THAT anywhere on the internet :)
But you do make valid points. I wonder, though, if the anti-spam battle will eventually lead to most servers doing some variation of 'whitelisting', and if , at some point, reverse DNS-HELO/EHLO-EDN will have to match. I dunno; my crystal ball is cloudy.
