It appears you have a DNS-based Email Blacklist configured, and when it performs a lookup on, a listing is returned and the email is being deferred. However, when I perform the same lookup, I don't receive a listing. Can you provide that part of your configuration file, please? – Andrew Ty. Apr 19 '13 at 4:31
Could you post full version of the log entry and all log entries with the same queue-id? – Andrzej A. Filip Apr 19 '13 at 8:30
What is your question? Have you searched on Google for "dnsbl map: lookup", and what does that tell you about dnsbl? – Stefan Lasiewski May 5 '13 at 15:55

The DSBL blackhole list went dead almost five years ago. You should remove it from your configuration.
