Need to change the reply-to email address for internal NDRs. NDRs to other mail servers go as 'postmaster@mycompany.com' , but domain mailboxes receive one of our Admins' email address, which he believes he setup at original EXCH SMTP install. TY

Are you running E2K7 or E2K3? Look at your Admin's SMTP addresses and see if he/she has the postmaster@yourdomain.com address.

Hi, Same question, whether you have Exchange 2007 or 2003 installed. If you have Exchange 2007, the Microsoft Exchange Recipient object is used to send NDR messages. It is controlled by MicrosoftExchangeRecipientPrimarySmtpAddress setting in the Org configuration (Get-OrganizationConfig). "Microsoft Exchange" is the branding for E2k7 internal DSN's.
