Yeh that might be it. I checked the changelog and saw that the DNS
changes were the only real big change between 3.2.1. and 3.2.2 so what I
did was installed 3.2.3 and replaced the Dns.pm with the version from
3.2.1. I'll know if that is the problem lies there later on today as
traffic load increases.
I grepped my logs from between the versions focusing on batches of 30
and I clearly see differences of 100 to 150 secs between 3.2.1 and the
later versions. If anyone wants to check their times use this
egrep -e"Batch \(30 messages\) processed in" maillog

Running spamassassin -D -t <quarantined file name> reveals a lot.
I'm running SA with the patch from
and the debug output made that one pretty obvious.
