I need to limit email traffic from a block of IP's from my spam filter company. Where do I set that up in Exchange 2003. I only want to allow traffic from a block of IPs that my spam filter company gave me.

Exchange Defender has a good outline as to where to set this. See 4/5 down the page under IP restrictions. First is Exchange 2007, followed by 2003:

I would also suggest Exchange Defender is an excellent service for spam, and virus filtering, as well as archiving, and mail backup service if you are in need.

Open Exchange System Manager, Expand to Protocols then SMTP, Open the Properties of the default SMTP Virtual Server and click on the Access Tab, then on the Connection Button.
Select only the list below and add the IP Addresses one by one.
Hello,

In ESM, expand your server then Protocols then SMTP. Open the properties page for the default SMTP server. On the Access tab, click Connection. Click "Only the list below" and add the IPS you were given.

This is what I was given, so that is 21 IPs right?
200.60.200.0/21 (netmask: 255.255.248.0)

No - the range is 200.60.200.0 through to 200.60.207.255

That is a load of IPs to enter
You don't need to enter all the IPS, you can just enter the subnet and mask by clicking "Group of computers".

Normally your spam host does not have quite so many IP addresses to add!!
