Every day I have email messages stuck in the que address to rockhurstT19@ruceci.com when I check to see who is trying to send this message the from address is listed as < > It looks like some type of spam messages trying to go out but its only a couple of messages each day and they are always addressed to the same person. Any idea on how to stop this would be appreciated. I do not have any other type of messages like this in the que. The server is setup not to relay. Thank you

Hi, Whether your organization has Edge Server deployed or the hub transport server has anti-spam agents installed. If the organization has anti-spam agents installed, you can set Sender Filter to block Blank Sender. Please restart transport service after configure the Sender Filter. For detailed information, please refer to the following article: How to Add Blocked Senders and Domains to Sender Filter http://technet.microsoft.com/en-us/library/bb123706(EXCHG.80).aspx Mike
