There is no white list in Exchange 2003 as far as I know.  However,
there are a few approaches you can take to help.

One is that you can use Group Policy to add a list of safe senders to
everyone's safe senders list.  
Here is a link from a quick Google search on "group policy" and "safe
senders list" with instructions.  I've done this - it's not hard.

e-mail-lists-throughout-your-organization.aspx


Another option - 


If the email always has certain unique keywords in the subject or body
and you are using IMF, you can use custom weighting to effectively white
list the email.  It involves creating an XML file called
MSExchange.UceContentFilter.xml, which you can copy and paste from the
documentation and modify to your needs.




Look in the release notes for SP2 or try Google.  Here is on article at
msexchange.org:

http://www.msexchange.org/tutorials/Intelligent-Message-Filter-version-2
-IMF-v2.html

The file would look something like this, using the "Change=MIN" setting:

<?xml version="1.0" encoding="UTF-16" ?> 
-
<file:///D:\ExchangeProgram\bin\MSCFv2\MSExchange.UceContentFilter.xml>
<CustomWeightEntries
xmlns="http://schemas.microsoft.com/2005/CustomWeight";>
  <CustomWeightEntry Type="SUBJECT" Change="MIN" Text="Unique subject"
/>  
  </CustomWeightEntries>

 



One other approach which I have used is to use the sender filtering
function in Exchange to create a pseudo white list.  It's not really
what it's supposed to be used for, but this method does work as long as
you aren't using sender filtering for anything now.

I can't recall where I read about this originally, and there may be some
caveats.  Try Google.

The basic idea is to add the sending email address to the list of
addresses to be filtered, but instead of deleting it, archive it.  Then
use a scheduled task to periodically move the archived messages from the
Filter folder to the Pickup folder.

The steps would be 

Open Exchange System Manager
Expand Global Settings
Right Click Message Delivery and go into Properties
Go to the Sender Filtering Tab
Check the box to Archive filtered messages
Check the box to Accept messages without notifying the sender
Leave the other two boxes unchecked
Add the senders you want to "whitelist"
Apply and OK

Then what I did is created a batch file with 2 lines (beware wrapping-
move starts one line, exit is the second line)

move "C:\Exchange\Mailroot\vsi 1\Filter\*.tmp" "C:\Exchange\Mailroot\vsi
1\Pickup"
exit


I made a scheduled task to run this every 30 minutes and it has worked
well.
