I´m running an Exchange 2003 server on my Home network.
It´s fully updated and running fine.
Lately I have been recieving alot of NDR´s.
I have been reading that I shouldn´t disable NDR because I could get blacklisted.
But at Technet, Microsoft encourages you to disable NDR.
My question is, is there a difference between disabling outgoing NDR and ingoing?
I should think it would be ok to accept incomming ndr and have the server not generate outgoing in case of false recipients?
Is that the way to do it?
Under internet message formats you can disable ndr´s, but is that for outgoing, ingoing or both?
If you can disable outgoing only, where do I do that?
I have set up spf records and that seems to have solved the massive ndr recieving, but I figured I might as well disable outgoing to spare others the problems with recieving ndr from my server.
I have been thinking to set up my real domain name under internet message formats and remove ndr from that one and leave the * as it is with ndr on. Would this be a bad idea?
