Uh -- the way OpenBSD deals with sendmail is a bit different to the way
FreeBSD does.
Under FreeBSD, rc.conf settings are used to prevent sendmail from
listening on any network interfaces than the loopback. Otherwise
exactly the same sendmail.cf would be used for either case. FreeBSD
also has all of the machinery required to rebuild the .cf files from
the .mc files setup and available directly from /etc/mail. The system
defaults to creating $(hostname).mc and $(hostname).submit.mc files if
none exist already and then turning those into sendmail.cf and submit.cf
