One possibility, assuming that you are using sendmail.mc as your 
configuration file, is this:

======== sendmail.mc ========
dnl changes sendmail to only listen on the loopback device 127.0.0.1
dnl and not on any other network devices. Comment out if you want
dnl to accept email over the network.
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
