How to set a transport rule on our exchange server to block receiving emails from a domain.

Hi

We have exchange 2007 and outlook 2010 and from last week we are receiving spam emails from and domain with .doc attachments.
I had asked our spam filtering team that are hosted outside to our network to block this domain. I was told that they have blocked and still users are getting emails from the same domain.
Please let me know if it is possible to set a transport rule on our exchange server to block this domain/a better way to sort this.
Please post me tutorials to set up this.

Thanks

You can block the entire domain by modifying the anti-spam sender filter in Hub-Transport.

This article takes you through the process. Be careful though - if we block a top-level domain, we will get NO email from that domain or any child domains.
