Hi In Exchange 2003, it was possible to set up a postmaster address on the SMTP virtual server that would recieve copies of NDR's for Exchange recipients on that mailbox server. With the Exchange 2007 GUI, I cannot see a way to do this. I have read the article here: http://technet.microsoft.com/en-us/library/bb400930.aspx And it seems to state that: i) A postmaster address can be set for internal NDR's, but this will apply to all Hub Transports in the entire orgii) For external NDR's, a postmaster address can be specified per Hub Transport server I had some questions; a) Could someone confirm that my understanding is correctb) Is it not possible to set a postmaster address for *Internal* NDR's as well, on a per Hub Transport basis? It seems a bit silly to have the internal NDR's for ALL Hubs going to one address? Thanks!!!

Hi,Your understanding is correctly.That could not be changed since the MicrosoftExchangeRecipientReplyRecipient parameter is only available for the Organization Configuration.ThanksAllen
