Use something like the following as the first line in the list file:
|if [ "$HOST" == "freestyleinteractive.com" ; then exit 0; else \
echo "you're not authorized to send to this address"; exit 100; fi
[lines broken for readability]
If the host is OK, qmail will deliver to the rest of the lines in the
file. If it's not, it bounces with the "not authorized" message.
