Why are you creating a mailbox just to forward to a contact? I have not does this with Exchange 2007, but a couple of years ago we did this in Exchange 2003 using contacts only. Create a new contact with the SMTP address of usern...@psnet.com and the External E-mail Address as usern...@bellsouth.net.
This should allow you to receive on the psnet.com address and redirect it to the bellsouth.net address. -----Original Message----- From: Phillip Partipilo [mailto:p...@psnet.com] Sent: Thursday, August 26, 2010 4:00 PM To: MS-Exchange Admin Issues Subject: Forward-only email address I'm stumped here. Trying to simply create an alias so usern...@psnet.com will forward to usern...@bellsouth.net, for example. I'm from a unix mailserver background and this is beyond extremely simple there. Alas, it seems not in Exchange (2007) (well maybe it is and im just too much of a noob). Ok, so I go into Recipient Configuration -> Mail Contact. I create a contact for this user with SMTP:usern...@bellsouth.net as the external email address. I then go into Recipient Configuration -> Mailbox. New mailbox. User mailbox. New user. Fill out details (by the way, the username will be different for each address, lets say un...@psnet.com should go to usern...@bellsouth.net) Now in Mail Flow settings, Delivery Options, Check Forward, select the contact that was made earlier. This works great if I send email to this box from within the Exchange organization, but any external user sending mail in gets a 550 User Unknown. Am I missing something here?
