I have an user with the email:
[email protected]
I'd like to also have him recieve his emails on:
[email protected]
Note that it is the SAME (1) domain I'm talking about. Another example would be:
I've tried adding the smtp adress in Email Adresses in AD, but it doesn't work.
Sending emails to [email protected] gives Delivery Status Notification (Failure). Error: 550 550 Invalid recipient <[email protected]> (#5.1.1) (state 14).
Current unsuccessful setup:
How do give an user multiple email aliases? I've googled for hours...
Since it works internally, check if you have some sort of edge device that only allows email addresses through that you enter into the device.
Your ISP may offer a similar service, or someone like MessageLabs also provide a similar service.
It works for me having multiple addresses added just like you did. Have you redirected other domain to your Exchange server (i presume by aliases you mean different domains)?
You also need to add it to Recipient Policies in System Manager as per http://www.petri.co.il/configure_exchange_2000_2003_to_receive_email_for_other_domains.htm
Your configuration is correct. However, it might take a while for these changes to be propagated. Patience is key (force update can probably be done as described in kb319065).
