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.
