Exchange  Inteligent message filtering (IMF) and Custom Weighting Feature  (CWF) not working in exchange 2003

I have a windows exchange server 2003 standard that I had configured with Intelligent Message Filter (IMF) and it was working OK but people were complaining that some viagra messages were coming through. People wanted to know if word filtering could be used to filter for the spam that was coming in.
I know that  IMF Ver.2 comes with a "Custom Weighting Feature" (CWF) and I decided to configure it. Well long story short once I did  the spam flood doors opened up and now all kinds of spam are coming into all the user's mailboxes.
My questions are:

1. how do I disable the CWF feature to get the IMF working properly again?
2. how can I properly configure CWF to work and filter out specified words.

Bellow you'll see the xml I used for the CWF .

Please keep in mind that I know NOTHING about the code bellow I simply copied it from an article and inserted the words I wanted to filter in place of the ones that were there before.
Thanks in advance for your help.

<?xml version="1.0" encoding="UTF-16"?>
<CustomWeightEntries xmlns=http://schemas.microsoft.com/2005/
CustomWeight>
     <CustomWeightEntry Type="BODY" Change="MIN" Text="viagra"/>
     <CustomWeightEntry Type="BODY" Change="Min" Text="cialis"/>
     <CustomWeightEntry Type="BODY" Change="Min" Text="him larger"/>
     <CustomWeightEntry Type="BODY" Change="5" Text="pills"/>
     <CustomWeightEntry Type="BODY" Change="-9" Text="Verlängertes Angebot"/>
     <CustomWeightEntry Type="SUBJECT" Change="MIN" Text="Pfizer"/>
     <CustomWeightEntry Type="BOTH" Change="MAX" Text="Offre spéciale"/>
</CustomWeightEntries>

Hi Bro,

Unfortunately there is no straightforward way to do reset IMF V 2.0 to v 1.0. But there is a workaround though:

What you need to do is basically uninstall all Intelligent Message Filter Updates that you have recived. They will be listed under Add/Remove Programs "Update for Intelligent Message Filter on Exchange Server 2003"  title. After you unistall the updates, IMF will return to default version shipped with Exchange 2003 SP2.

Have fun and Best of Luck :)

Thanks for the help. I did not re-install it since it was useless to me.

Setting the Change attribute to MIN in the custom weight entries will cause IMF to allow all messages containing the text in the Text attribute to pass through the spam filter.
In your case all messages containing Viagra, cialis, him larger, Pfizer, and/or Offre soéciale will pass through IMF.
Isnt this the cause of the problem?
