Hi,
yes I got an 477 and fifo list_blacklists on dispatcher layer shows:
(I have LB and SP running on two hosts, LB on 5060, SP on 5080)
Having #disable_dns_blacklists=yes in my config.

LB #1 <IP #1>:
List:: dns owner=17 flags=6
        Rule::  flags=0
                IP:: <IP #1>
                Mask:: 255.255.255.255
                Proto:: 1
                Port:: 5080
                Expire:: 7089
        Rule::  flags=0
                IP:: <IP #1>
                Mask:: 255.255.255.255
                Proto:: 1
                Port:: 5060
                Expire:: 7092


LB #2 <IP #2>:

List:: dns owner=17 flags=6
        Rule::  flags=0
                IP:: <IP #1>
                Mask:: 255.255.255.255
                Proto:: 1
                Port:: 5060
                Expire:: 7064
