If you still want mail to work, but don't want to listen on a network
port:
cd /etc/mail/
make
vi `hostname`.submit.mc
Change the 127.0.0.1 in the line "FEATURE(`msp', `[127.0.0.1]')dnl"
to an IP address that has a listening SMTP server and will accept
mail from your jail. You can also use a hostname, for example,
FEATURE(`msp', `smtp.example.com')
make install
Then make sure you leave the default for sendmail_outbound_enable ("YES")
and turn off the others. You'll have a system where mail works just fine
and nothing listens on any TCP port.
