Bouncing an undeliverable mail is not "no actions". qmail treats an
undeliverable message trhe same as it treats any other mail: it does
everything it can to deliver the message *intact* to *someone*. That
message may contain the only existing copy of some valuable data...

No, not without patching qmail, because qmail-smtpd is just not able
to tell which addresses are good and which are bad.
