No, but I recently added a herustic to my antispam milter that a host
which says "HELO hotmail.com" that has no reverse IP address probably
isn't hotmail.com, so I refuse it.  In the case below, such a rule would
have helped you.  :)  I've also decided that hosts without a reverse DNS
name which say HELO <word>, where <word> isn't a domain name, are
probably spammers.  There has only been one notice of a misblocked
email, so I'm leaving it in place for now.  Lastly, since most Korean
and Chinese spammers don't seem able to configure DNS, but give helpful
hostnames in their HELO, I block certain HELOs from repeat offenders
(like 163.net and 163.com).
