Better yet, set up a /etc/mail/relay-domains file and then add just those
customers using their IPs. You can use specific IPs if they will be so or
include whole groups by cutting off the octets:

200.101.107.111 <== specific
200.101.107.    <== broaden group
200.101.        <== broaden even more

After you have the Ips loaded, restart sendmail....
