We are running SBS 2k3 with exchange 2k3. Recently when I try to send an email to a particular recipient, I get the following error:

<xxxx.com.au #5.7.1 smtp;550 5.7.1 Message rejected as spam by Content Filtering.>
I get this same error when I send it to any of the staff for this company. I can send an email to any other company fine just this one I get the above error.
Does anyone know where I can change my settings in exchange system manager for content filtering or any where else to overcome this problem.
Any help would be greatly appreciated.
