Exchange 2003 SBS Still getting spam

I currently have SBS2003 and I have exchange installed. I installed GFI mail security and we have been getting a lot of spam. How can I check if there is something else wrong on the exchange server side.

Installing is one step... have you CONFIGURED GFI?  Setup RBLs?

Nope, just how do I do that

lets stop the Spams :
check if the server is open for relay. properties of Default smtp virtual server ->access tab--> relay
you should have the first option selected there.
and then do the following :

Follow this :
1) fist and the formost thing is to enable all the spam filterings on the exchange server :

--> On the properties of Message Delivery under Global Settings in the Recipients Filtering tab checked the 'Filter recipients who are not in the directory'
--> On the Sender Filtering tab checked the 'Filter messages with blank sender'
-->  On the Connection Filtering tab added a rule in the Block List Service Configuration as a display name of Spam Haus, DNS suffix of zen.spamhaus.org and on the return status code clicked on the Match filter rule to any of the filter responses and added the IP address from to with an exception
of, and
-->  On the IMF tab changed the Gateway Blocking Configuration threshold to 7 and Archive When blocking messages and the Store Junk Email Configuration threshold to 6
-> then go to properties of default smtp virtual server--> general tab-->advance button--> edit--> and check mark all the filters except sender id filtering.................

-> enable tarpeting through the registry path :
-> NOW we wil add a regustry key so that if the spammer is using any kind of script exchange will break it....HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SMTPSVC\Parameters and added a deword value TarpitTime and gave it a value of 5.

2) now stop the SMTP service. and go to "C:\Program Files\Exchsrvr\Mailroot location and rename Mailroot to MailrootOLD.
3) restart SMTP...... check the mail flow and monitor the queues......
