I see that all the time.
For me, blocking helo with with $inet_interfaces/$myhostname is
not sufficient, since Postfix does not know everything.
More useful is to block any helo name/address that resolves to an
address on the local network when the client is elsewhere, but
that is not as simple as suggested in this thread.
