Hello We are using Exchange 5.5 with SP4, and there is a attachment size limit of 5 MB to send and receive. When ever any sender sends mail more then this size he/she gets NDR stating the cause of over size, but Administrator don't get any notification. Is there any way to get an alert for Administrator or some log entries where Administrator can search the delivery failure due to over size? I will appreciate your quick reply.
