Are you sure you receive this email and your users are not sending them? Because I think the sendmail.cf in FreeBSD automatically blocks relaying as default by starting at version 3.1 I guess. how does your users send mail? they login to the machine and send or via smtp remotely? As it comes to m4 configuration I found it easy to go to /usr/src/contrib/sendmail/cf/cf and then fallow the instructions on sendmails web page (if you installed sources you can have this directory) there are also some sample configurations in there.
