I hate to get into a "it does ... does not ... does, too" type of
argument with you again, but qmail 1.03 (the last official release) does
not do this. It accepts all mails for all domains in (more)rcpthosts and
hands them to qmail-queue to put it into the queue. There qmail-send
will pick them up and try to deliver them (via qmail-lspawn and
qmail-local for local users) and send a bounce message if that fails
(I think it's qmail-send. The man-page doesn't explicitely state that it
sends the bounces, but all the bounce-related controlfiles are
documented there).
qmail-queue can't cause a failure for RCPT because it is called too late
for that.
You may be thinking of some unofficial patch for qmail-smtpd.
