Deny accepting mails from a specific domain

Is there a way in Exchange 5.5 IMS to reject mails coming inbound from a certain domain?  For example, I want to block/reject mails coming in to my company from abc.com.  I couldn't seem to be able to find it in the IMS.  Does it have this capability or I'll need to get a third party software.  
Your answers would be appreciated.  Thanks in advance.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Go with the freeware version of the product. It's just to easy to implement to not recommend it. Won't cost you a dime.

Or, simply use the Connections tab to block senders by domain. On the IMC, Connections, then click message filtering. you can specify a turf directory to archive the blocked emails, or as I do, just delete the messages. you'll need to restart the MTA and the IMC for it to take effect.

Clear answer, Kidego.  But what if you want to filter out all messages from, e.g., .BIZ domains.  Is there a way to use wildcards to do this?
So far have tried *.biz  etc. without success.
