Look for the check_* rulesets (probably at the end of sendmail.cf),
and delete them. However, spammers will then be able to use your
server to relay spam. This may result in other domains refusing to
accept any mail from your server.

This is the wrong file; it's ip-allow and name-allow which are
relevant. If a domain is in relay-allow, anyone can send mail to it
via your server. This is for use if your server is a backup MX for one
or more domains.

Yes.

If you add the IP addresses of the hosts on your network to the
ip-allow file, they should be able to send mail to anywhere. I think
that you can specify part of the address to allow the entire network
to use the server as a relay.
