In this case the intention is not to block an IP, but to make a policy
decision e.g. "if the IP is listed, amavis should not scan it for SPAM" or "if
the IP is listed, it should use a policy bank with higher SPAM scores".

The DNS(BL) mechanism is only used as a network based lookup table. Easy to
distribute and it doesn't require a reload of all amavis instances 'reading'
an IP list.
