Have you turned the Anti-Spam feature on?

1) Expand Organization Configuration then Hub Transport
2) Click on the Anti-Spam tab.
3) Right click on Content Filtering and choose properties
4) Go to the Action tab and setup the SCL ratings

I have mine set for Delete at 9, reject at 7, and send to Spam@domain.com at 5.  It's working well for me.

do i need to create separate mailbox  like spam@mydomainname.com.

Also is there any option to send notification mails to users where they can see the spam mails which they have received. Like in Barracuda spam filter

Yes you do need to create a spam@mydomainname.com account.

No, there's no way to send notifications to the users.  It's a very limited (still a good price for free) spam filter.  If you have a barracuda spam filter that has worked well for you in the past then as long as it's compatible with Exchange 2007 I would use it.

I am geeting below message in my edge server...


the query produced too many results. To reduce the number of results, use a more restrictive filter.it was runnung command get-message -ResultSize "1000' -Returnpageinfo $true -server Edgeserver.dhcc.mazaya.com -SortOrder -FromAddress -SearchForword $true-BookmarkObject $null -BookmarkIndex '-1'Includebookmark $false

Please advice what to do next.

In the queue you can clear queues by right clicking on them and choosing Remove Messages.

As far as your error message goes.  It looks like you were trying to use the Message tracking and the filter you were using was to broad and gave you more responses then it could handle.  

If you open Exchange power shell and use the get-message command then you can by pass this by changing the -ResultSize to 9999.  You also need to export the data so you can read it.  Ad the end of your get-message command put in | export-csv c:\exchangereports\userstats.csv.  This will allow you to open the file with Excel and read it.

The following link explains more about the get-message command.

That address has been spoofed.  To reject this type of spam change the settings to your Sender ID.  This setting is in the same location that the Content Filtering was in.  To change it right click on Sender ID, then choose properties.  Click on the action tab and choose Reject message from the list.  Then click on OK and it should apply that setting.

Let me know if that helps.

You could lower the SCL ratings by a couple numbers and see if that helps.  Just make sure that you are keeping a close eye for any false positives.

Then your only option left is to purchase a 3rd party spam solution to filter out the spam.  I've heard good things about the barracuda spam filter.

But as far as filtering out the spam with the Exchange server tools, you've done all you can with the limited tools that Exchange has.
