I have exchange server 2003 SP2. The default policy doesn’t allow automatic forward. But I created new Contact under ADUC with external email address (email@example.com) and modified it Override Internet Mail Service setting for this recipient. Then from the my company user account under Exchange General>>Delivery Option>> point to forward to the contact I created earlier and checked the box Deliver message to both forwarding address and mailbox.
The problem is when I tested sending email for any External account to my company email account, it received on my company account and don’t receive copy on the External account (Contact created earlier (firstname.lastname@example.org)), and the original sender will receive message :
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
Arrival-Date: Wed, 5 Jul 2006 09:48:28 -0700
Final-Recipient: rfc822; Email@yahoo.com
Diagnostic-Code: smtp;551 This is not a relay host - mail must be to or
from host domain.
FYI: when I send email from any my company email account, both accounts (internal and the external) receive it.
Thanks in advance!
