I am using a Sophos Firewall and Exchange 2010 Server and I am discontinuing a domain and want an ndr/reject message  to  be sent to  the sender that the e-mail is no longer valid.
I am not sure where to make this happen.. do I discontune domain in Sophos have exchange send the NDr or what are the rules of the internet to where the message will be rejected.
When I delete the domain in sophos I get a message bounce back that says relaying not allowed.
I want the sender to get an email not valid message.
Thanks

When you decommission your MX records on your external DNS when people try to send you email they will automatically get a bounce back stating the email/domain does not exist. No need to send out a NDR notice. As soon as they try to send mail they will be notified.
