modify NDR so it does not show the internal mail servers FQDN or allow me to put in a different FQDN

Hi

We have 2 companies sharing a single domain and using the same mail server (Exchange 2007) one of the companies have raised the fact that when people get a bounce back it shows the other company's domain (as the internal domain is based on that company), i have paseted it below.

 The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.
            <company1.local #5.1.1 smtp;550 5.1.1 RESOLVER.ADR.RecipNotFound; not found>

Is there a way i can change this behavior and change the domain to a generic domain name, if so is there any risk in doing this.

Thanks

Nick

Changing NDR message may mislead in troubleshooting so there is no easy way to do this and Exchange Server does not allow this.

Any organization which receive NDR message from your organization can see only the Internet Facing Mail Server which is throwing message back.

And changing the NDR really doesn't help in increasing security because anywas message headers contains names of the internal mail servers.

Thanks SmartSid,

I didnt think it would be an easy fix. I will remove any NDR's that are not essential but they will have to live with the defaults for troubleshooting .

Thanks again
