We have Exchange 2010 with the built in SPAM filter installed. Was wondering if there is a way to check what messages have been blocked. We have a customer trying to send an e-mail and it never shows up. I suspect that the customer may have been black-listed by SPAM-COP. Also, is there any way to allow mail from the customer's domain to get through the Exchange 2010 spam filter.
Any help is greatly appreciated.
