Emails from one of our clients, located in Egypt, are not delivered, whereas they are delivered to hotmail or dot Mac.
Is there any reason why Exchange would not let them through? We also run McAfee GroupShield 6.0 (checks Black/White List Server at: http://bl.csma.biz
), but I have searched the Detected Items database for the sender address and nothing crops up.
I am just enquiring if there are any filters or settings in Exchange I need to know about.
