Don't accept mail from home networks. For example, use "reject_dbl_client

not, unless they are listed in zen.spamhaus.org, which should not happen.
Zen includes the "PBL" component, which consists largely of residential and
mobile consumer IPs.
The ZEN response codes say which data-set(s) list the IP address; you can qualify the "reject_dbl_client" directive to
disregard the PBL component.
The other components will remain active, and contribute to the blocking process.
