That's what has been discussed - it can't be done in the current state, cause the MTA gets stuff in batches, not just one message at a time.

That will work for maybe 10% of addresses.  I know that none of my many internet connections reverse lookup to anything close to my email address domain.  That includes the machine IP address, as well as my mail server address.

Unfortunately, no simple way around it.
