email - Exchange 2007 mails blocked debug

we are running sbs2008 with exchange 2007. One user suddenly can't receive emails from one external sender any more and the sender never gets a return email. That user has to use hotmail or gmail etc to send to that sender.




I am thinking must be blocked in somewhere but could not find it. Any direction can point me to? Thanks.



Update 1:



With Exchange Troubleshooting Assistant, I track down all mails sent from that sender, have been marked spams in the subject:



***SPAM***



I guess the spam then be deleted by server quietly?? I will need to check spam settings and come back later. Thanks.



Update 2:



I found in Anti-Spam -> Content Filter:
If the message contains "SPAM", will be blocked.



Option1: Is it a good practice to have this kind of setting here? because no one is acknowledged about this deletion. On the other side, if I remove this policy, I may get hundreds of SPAM in our Inbox.
Option2: How do I define a while list, so mails from certain sender will not be marked as SPAM?




Update 3:



OK - I am totally cool now.
I am using this GUI tool to manage the whilelist for anti-spam:
