Do not relay mail for their netblock, just provide backup mx functionality for their domain. In sendmail terms that means removing their netblock from the access db.

No thats not correct actually you need to put the domain name in /etc/mail/relay-domains and set your mailertable to point to the primary MX bypassing DNS
