Re: UMSY

I've done a little more research on the flood of false negatives making it 
into my SC inbox, and although all of the IPs I've checked so far are 
listed on the CBL, the listing times were less than half an hour before 
their arrivals at the SC mail servers, so maybe the SC servers aren't doing 
"realtime" queries of the CBL when processing incoming email? Here's an 
example:

CBL lookup:
IP Address 221.199.146.98 was found in the CBL.
It was detected at 2006-03-09 12:00 GMT (+/- 30 minutes).

Spam received:
  by mx53.cesmail.net with SMTP; 9 Mar 2006 12:32:40 -0000

So, although if things were functioning ideally, that spam should have been 
blocked, we might be looking at stuff that's getting by just under the 
wire, before the SC system can tell that the CBL is listing them.
