Look in your /etc/mail/sendmail.mc file for something like the following:

dnl # The following causes sendmail to only listen on the IPv4 loopback
address
dnl # 127.0.0.1 and not on any other network devices. Remove the loopback
dnl # address restriction to accept email from the internet or intranet.
dnl #
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
dnl #

The line that binds it to loopback is the DAEMON_OPTIONS line. comment it
out like this:

dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Save that change, and you should be able to run "make -C /etc/mail" and
restart sendmail. Thats it =)
