to answer my own questions and for future reference to who anyone else who
comes across this problem you have to include

FEATURE(`accept_unresolvable_domains')

when building the macro in the sendmail.mc file to create the sendmail.cf
file. If you include FEATURE(`access_db',`hash -o /etc/mail/access.db')
aswell then it will still check against the IPs, Domains, etc but wont fail
when relaying for IPs it cant perform a reverse lookup on.
