I have Spamhaus in
front of invaluement in
my postfix configuration but I may try flipping the order just to see
if it will start blocking more
than Spamhaus.
with postfix posttscreen one can test all ips on all rbls in same single
smtpd client check, so there is no just spamhaus here :-)
despite its called dnsbl in postscreen it supports whitelist aswell
for me i have keeped all rbl checks from spamassassin into postscreen, i
know there is more rbl lists i could add, but for me there is no need
to, to many quererys makes to much dns trafic without more usefull data,
and to make it more stable its nice that postscreen cache results on
positive hits a little longer then ttl in dns
