I'm getting this error when trying to forward an e-mail to another address in our domain:
Your message did not reach some or all of the intended recipients.
Subject: FW: test
Sent: 8/6/2008 2:35 PM
The following recipient(s) cannot be reached:
Test User on 8/6/2008 2:35 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
The user trying to send from is as follows:
Username - Bob Testman
Primary e-mail address: SMTP firstname.lastname@example.org
Alternate addresses: smtp email@example.com
This only happens if in the 'from' field I put something other than firstname.lastname@example.org. Using 'email@example.com' in the 'from' works fine, no errors. 'firstname.lastname@example.org' does not, however.
I have tried changing the SMTP virtual server properties in the Exchange system manager, and setting authenticated users to have relay permission but it didn't help. I have also given this user full permissions in active directory, and full mailbox rights... still nothing.
Should I just tell this user to only specify the primary address in the 'from' field, or is there a way to make them all work?
