Exchange 2k3 all svc packs with spam and antivirus (symantec.)
I am having NDR's forwarded to me. While this is ok, some of these messages I have configured the exchange server to delete immediately if they are to specific addresses that I know don't exist. If that is the case, should I still be getting NDR's for them? Or are they deleted usually by spam like symantec after the NDR hits?
Also, I got about 50 of these in one night to all different names that don't exist at my organization. Does this mean I am under attack? Is it affecting performance of the server? How best should I handle these? Ignore them? Is anyone familiar with getting lots of these?
