Oh. Now I see. :-}
Sorry for the confusion.

Actually I probably benefit from your patch, because I actually have
this condition inside a "warn" block. (I don't reject the mail right
away, instead I set $acl_m0 and impose 20s delays in every ACL until
finally rejecting the mail after DATA).

That said, maybe it is _desirable_ to give 451 responses to hosts that
HELO using unresolvable names... :-/
