There should be a file /etc/init.d/sendmail.dpkg-new -- you might want to
replace the /etc/init.d/sendmail file with this one so that it looks in
the right place.

This relaying protection is actually something that you definitely DO
want. If you're running sendmail open to all relaying on the Internet,
before long some spammer will discover it and happily steal your bandwidth
and cpu to send their crap all over the Internet, possibly resulting in
the blacklisting of your mailhost stopping you from mailing about 30% of
the net.
You should be able to use appropriate wildcards in the relay-domains file
so you don't have to do it by host, but by IP ranges (172.16.*) or whole
domains (*.example.com). Yes it's more of a pain than unrestricted
access, but having your mailer exploited by spammers is more of a pain
than anything (and many people will dislike you for it.)
