Hi, a client sent a message that was returned as 'undeliverable' because of security policies. I am wondering where on our exchange server 2007 I can view incoming messages to investigate why this message was blocked and possibly to allow through to the recipient? Many thanksJonathan

Hi Jonathan, There could be many reason to NDR this email. If you share detail NDR then we can help you more. NDR will give you correct information. You can also check message tracking log to see if this mail is deliverd till exchange or NDR'd from your gateway only. If you have spam solution in place then you can see log of spam and viruswall also.Anil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com
