Running E2K3 on Server 2K3 R2. I have created a user with a SMTP email account only. All my other domain users have exchange accounts. (I did this for reasons that would take too much space to explain, can't use OWA). I want only three internal users to be able to send email to this address, then about five (this number will grow) external addresses (AOL, etc) to be able to send to the address. We have our own domain, mx record etc, so I am not working though an ISP.
In delivery restrictions, I checked the ONLY FROM box, and added the internal addresses. For the external addresses, I created contacts for each address, then added those to the ONLY FROM box. Internal works fine, users not added get a security message when they try to send, allowed users can send. Problem is the external users get the following message, or something similar to it, I have tried several accounts:
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 sorry, no mailbox here by that name. (#5.1.1) (state 14).
If I change the restrictions to FROM EVERYONE, all external mail gets through without issues.
This is the first time I have setup an internal POP\SMTP mail box, so I could be doing any number of things wrong. Any suggestions appreciated.
