Some recepients couldn't be reached
Posted on 2006-11-27
I have a Problem for some Exchange users in my organization.
For some users, when they try to send to some emails outside the organization they get:
Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:
email@example.com on 27/11/2006 4:10 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mymailserver.com.eg #5.7.1 smtp;542 5.7.1 Mail relay not allowed at this server>
This only happens to Some Users when sending to Some recepients, this's not persistent. I searched the SPAM DB's and my mail server is not listed on Any of them.
