Recall my recent thread about this. I had switched my resolvers to Google
public DNS and it broke zen, silently in my case.
Once the fine folks here helped me figure out the problem, and upon resulting
recommendations, I installed pdns_recursor on my postfix MX and all is good with
the dns/rbl world once again. ;)
pdns_recursor is tiny and miserly on resources. Set its cache to like 8192 and
forget you installed it. Works great.
