You know what? You do it from sendmail, and people will immediately
write simple SMTP clients in any language of their choice and send emails
where ever they want. In fact, I think /bin/mail does this already. IIRC, so
does pine.
The easiest thing to do is to run the command
/sbin/ipchains -I output ! --dest 127.0.0.1 --dport 25 -j REJECT
on the server. Sendmail will send back an apologetic mail back to anyone
who tries to send mails outside saying that it was unable to help them.
