All SMTP checks are disabled for those entries (e.g. Greylisting,

SPF, DNSBL, ...)
DNSBL checks are done by `postscreen` which works on IP addresses and networks.
This means it can only make use of the `IP Address` and `IP Network` entries.
NOTE: If you use a backup MX server (e.g. your ISP offers this service
for you) you should always add those servers here.
NOTE: To disable DNSBL checks entirely, remove any `DNSBL Sites` entries in
xref:pmgconfig_mailproxy_options[Mail Proxy Options].
