Email getting blocked.
Posted on 2014-12-23
Currently our corporate users are blocked from being able to email firstname.lastname@example.org. This creates an issue if we need to forward an email from that address to a corporate user who wants to reply back. All corporate users should be able to email this address which is a shared mailbox used by online customer service.
Our environment is Server 2003 for Exchange and running Exchange 2007. The email email@example.com is hosted by Godaddy. The issue is that we can receive emails from firstname.lastname@example.org but when we try to send an email we are getting a denied sent due to restrictions. Our Websense is not blocking it.
See below (Bounce back message). I modified a few things in the bounce back message for security reasons. Anyone who has ever troubleshot this issue, please shed some light on how to fix or troubleshoot. Thank you.
