You are right, and the FAQ is wrong.

To whitelist mail from the single mailbox such as,,
use a line like this:

  OK      env_From

With the contents of /var/dcc/dcc_conf that are in the official source
(i.e. not from a third party), the following line will whitelist mail
from all mailboxes at the domain name:

  OK      substitute mail_host

Thanks for pointing out the FAQ error,
