Not all of them, mind you. I use the following on my laptop:
sendmail_enable="NO"
sendmail_outbound_enable="NO"
sendmail_submit_enable="YES"
sendmail_msp_queue_enable="YES"
A fairly good explanation of why this setup works only as a 'local MTA',
and doesn't accept incoming SMTP connections from the world can be found
in the manpage of rc.sendmail:
% man rc.sendmail
To the original poster:
Feel free to use the above sendmail_xxx settings in your `/etc/rc.conf'
file, but please make sure that you also:
... understand why these settings make Sendmail only forward locally
generated email messages, by reading the rc.sendmail manpage.
... have configured properly your local `/etc/mail/sendmail.cf' and
`/etc/mail/submit.cf' files.
... read the Handbook section about Sendmail, and let us know if you
find it difficult to understand, or you would like to see more stuff
documented.
Cheers,
Giorgos
