URIBL_BLOCKED shows you are using still a dns-forwarder and so won't get
results from a lot of blacklists

http://uribl.com/refused.shtml

fix that - use a local caching resolver with *no forwarding* and if you
are using dnsmasq just don't do that for a inbound mailserver


I found an instruction here for a debian system

https://manageacloud.com/configuration/local_dns_caching

/etc/resolv.conf
nameserver 127.0.0.1

/etc/resolv.dnsmasq
nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 208.67.222.220
nameserver 208.67.220.222

/etc/default/dnsmasq
DNSMASQ_OPTS="-r /etc/resolv.dnsmasq"


But it is using dnsmasq for local dns caching. I ve configured it, but I still see URIBL_BLOCKED=0.001 in a mail header.

with local caching it s a bit faster
# for i in {1..100}; do time dig slashdot.org @localhost; done 2>&1 | grep ^real | sed -e s/.*m// | awk '{sum += $1} END {print sum / NR}'
0.0076


# for i in {1..100}; do time dig slashdot.org; done 2>&1 | grep ^real | sed -e s/.*m// | awk '{sum += $1} END {print sum / NR}'
0.00962

Seems to work local dns caching but I dont understand why I shouldnt use it for inbound mailserver and why I still see URIBL_BLOCKED=0.001
