Postfix was not set up. Start with
  cp /usr/share/postfix/main.cf.debian /etc/postfix/main.cf
. If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed. To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.
