The original thought behind the option that you just disabled was to
restrict where the sendmail listened for connections , so that it wouldn't
be an open relay ( relaying , sending emails to the whole internet for
everybody , even spammers ) .  So i guess you would have to reenable
the above option or edit access.db , so that your sendmail would relay 
emails
just for you and not for the entire world
