Well, qmail does per default (i.e. without a patch) accept all messages
for the domains it handles and sends bounces for non-existent users.
While this generates extra load, it is not just dumb to do it this way.
Rejecting mails for unknown users at SMTP level gives a clever spammer
the chance to validate addresses. Every recipient that does not produce
an error is valid. I do not know if spammers do that, but it would be a
cheap address validation service.
