Hi,

how about using the /etc/hosts.allow file. I have for example the
following line there (among others):

exim : LOCAL

which restricts conects to the exim mta service (port 25) to local
conections. sendmail seems to be linked against libwrap0, hence I gues, it
will respect a 

sendmail : LOCAL

entry there (or somthing similar). more informations can probably be found
in the hosts_access (5) and hosts_options (5) man pages.
