I seem to have discovered a new mechanism for generating SPAM. I am of late receiving lots of emails addressed to non-existant users. These names could not exist on our network or anyones for that matter! So I suspect they are using it as a mechanism for generating 'noise' on the internet.
Is there any way to disable the NDR in Exchange 2003.
