Spam being missed completely and not recorded in any logs on UT

Hi folks,

I'm experiencing a strange symptom with UT 10 64-bit, the latest as I installed it three days ago.

So, here goes, the UT firewall works very well for the most parts. I'm using the subscribed Spam Blocker rack feature.

My configuration: http://screencast.com/t/vH7dtlMgLsv

I'm seeing a bunch of spam messages just flying through into my mailbox and definitely coming from the outside and is not even being picked up by the Spam Blocker at all. Logs are not showing any record of certain spam emails whatsoever. Like, there would be a spam message that flies right into my inbox (viewable by webmail) and shows no record of it being picked up by UT. There have been a number of these flying right through ever since I changed from 9.4 to 10.

I am using it in this configuration: (Internet) <-> UT 10 (Transparent Mode) <-> Mail Server

There are no warnings at the top of the rack suggesting any DNSBL lookup issues.

I am using internal DNS that resolve correctly only to my known IP addresses.

By the way, date range in the Event Log for any rack item, when setting from and to dates for lookup, do not work, no matter what I do.

Thanks for any insight.
