I guess you can make qmail act like sendmail, but sendmail still isn't
/bin/mail. :) But in /var/qmail/bin there are plenty of other
"wrapper" type programs. Here's the same code from above, modified to
work with /var/qmail/bin/mailsubj, which takes input from stdin and allows
you to specify a subject and a recipient.
cat $TMPDIR/checkreport.$$ | $MAIL "$HOSTNAME $DATE ACTIVE SYSTEM ATTACK!"
$SYSADMIN
