The log below is for a connection from that started 03:46:32.
2012-07-30T03:46:32.620614+02:00 02as postfix/postscreen[1276]: CONNECT from
[61.247.33.244]:2163 to [158.102.109.68]:25
postscreen waits for five seconds, and receives no DNSBL result.
It therefore puts the client on the whitelist (PASS NEW).
2012-07-30T03:46:41.570129+02:00 02as postfix/postscreen[1276]: NOQUEUE:

The DNSBL results arrive after postscreen has decided that the
client is not blacklisted.

You need to fix your DNS, run a local DNS server, or increase the
postscreen greet-wait delay.
