Anti spam Filters not working at all????
Hi,
I have set up Exchange 2007 on a 64bit Windows 2008 platform. All latest SP's applied etc..
I have only the 1 server and have used the command applets to configure the anti spam. I have updates working properly, the latest updates came in at 9:20 this morning accrding to the event viewer. Everything looks like it is set up but it is not stopping spam!!!!!
Topology:
Mail comes through our ISA server to our Exchange 2003 server. For those few mailboxes which I have migrated to 2007 it is then sent on via connectors etc....
2007 server only runs the Hub transport but I have manually set up spam.
In the shell I have run some tests - here are the outputs:
[PS] C:\Users\mattadmin\Desktop >get-conte ntfilterco nfig
Name : ContentFilterConfig
RejectionResponse : Message rejected as spam by Content Filtering.
OutlookEmailPostmarkValida tionEnable d : False

So you can see it is set up to use the spam.quarantine mail box for messages with an SCL > 5 for all message sincluding internal. (I have tried this set to 2 but still no joy) I turned of Outlook Postmark Validation to try and increase the spam score!!

A bad word to test with!!! )
OK - in testing this I find than all mail messages, both internal and external, which contain the word slartibartfast are being delivered, not stopped as spam. I cant see why this is happening?
When I look at the headers of the message delivered to the test mail box I see this - (Plus usual header stuff):
X-MS-Exchange-Organization -SCL: -1
X-MS-Exchange-Organization -Antispam- Report: MessageSecurityAntispamByp ass
For external messages it looks like this:
X-SpamReason: No, hits=0.4 required=7.0 tests=FORGED_HOTMAIL_RCVD,
and
X-MS-Exchange-Organization -Antispam- Report: MessageSecurityAntispamByp ass
X-MS-Exchange-Organization -SCL: -1
Don't understand the top line! Required=7??? I set it to 5 as you can see above!
Can anyone see where I have gone wrong? I don't understand why these messages are bypassing the spam scanning? I have not set up any bypasses. How do I check this?
Any help would be very much apreciated, this is driving me mad!
Many thanks
