Think about it, there is no difference sending to a local smtp sender
as it is to send to a remote smtp sender.  If it used the local inject
(i.e. the /usr/bin/sendmail -t command) qmail would break the system
since it does not have a sendmail command.  It doesn't break.  So, it
sends to the smtp address given it.  If you simply tell it root, it
assumes root at localhost, and contacts port 25 on the localhost.  If you
give it a fqdn, it uses the standard resolver.  I do not run sendmail
on any machine, and postfix on the mail server only.  I get my daily
logwatch messages, and other notification from cron on all machines.
