It's been many years since I used sendmail (I heavily recommend postfix) but I think if you edit /etc/mail/sendmail.mc and find the section... 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 and chnage the last line to dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl and restart sendmail to enable it to listen on all your network interfaces. Note that you then have to edit /etc/mail/access to control who can 'relay' email (and restart sendmail again). also note that generally running your own smtp server requires you to have a dns server so you have an mx record so it becomes obvious which server receives e-mail for your domain.
