Currently DNSBL is set on a server level by using:
- Additional Antispam Methods -> DNSBL

Then those DNSBLs are used for each and every domain one has configured on a server.

I would like to propose the possibility to configure different DNS block lists for different domains. After all, not all domains need/want the same level of spam-DNS blocking.

This feature would give MSPs and email hosting companies the possibility to fine tune the DNSBL spam response of the server for particular customer/domain in regards to their (customers) needs.
