Doesn't Postfix also behave in the same way?  Seems to me that pretty much
any MTA whose port 25 listener is running unprivileged is going to have
the same problem unless you want to periodically build a database of valid
addresses or require that all information necessary to determine whether a
given address is valid be world-readable on the system.
