(*) Please keep in mind this is for one of the systems I maintain - who has
a very wide diverse set of mail. Your mileage may vary.
Here are some stats gathered with DLAnalyzer on Zerohour.
***This is only a one day analysis.
* Triggered on 42,013 messages out of 99,842 total messages
* 40K of the 42K hits were on messages already considered spam and held.
* Out of the 42K Zerohour detections 39K of those were also detected by
Sniffer.
* DLAnalyzer's test quality rates Zerohour as .95. (SEE EXPLANATION BELOW ON
THIS)
* Zerohour triggered on 1,020 hams. In my visual those hams a good portion
were false positives on bulk solicited mail (Home Depot, Marta Stewart,
USDA, GOP Senators, Democratic National Committee, etc). I can go into more
detail on this if anyone wants more info offline.
For those that do not use DLAnalyzer it has a built in test quality report.
The test quality score is based on a -1 to 1 scale where -1 indicates HAM
and 1 indicates spam. The closer to 1 the more likely the test is at
detecting SPAM and the closer to -1 indicates HAM.
Other Test's Test Quality Scores
Message Sniffer - .99
invURIBL - .99
Zerohour - .95
Spamcop - .94
MxRate Black - .93
Fiveten - .92
Sorbs Spam - .71
At this point I have not evaluated CommTouch's false positive reporting.
That portion of my testing will come very soon.
Are any of my results scientific - no. Will I be dropping Message Sniffer -
Absolutly not. Will I continue using CommTouch - yes - as I think it has a
place on my system. Will your results and conclusions vary - absolutly.

If Pete doesn't mind I will post my observations in regards to the product.
I run both products (CommTouch and Sniffer).

I'm dying to start a thread and talk about Sniffer's stance on CommTouch,
but I can resist.
Instead, I would like to point out that eight clearly spam messages have
made it through to my Inbox [or Outlook Junk Folder] so far this week that
appear to have skinned clear through Sniffer. First ones I've seen in > >Are we undergoing a new phase or campaign that I can make adjustments for?
