How to allow internal SMTP in Windows Server 2003 SBS?
Posted on 2009-07-02
I am sure this is something simple that I missed. I am running Server 2003 SBS. Server IP as 10.10.10.10 recently bought a new Mitel switch (10.10.10.41) that needs to communicate to the server via SMTP. By deault, I don't think the Server is allowing internal addresses. I am getting "CSMTPClientMsg::ProcessResult - Failed sending Voice Mail to Email" & "CSMTPClientMsg::ProcessSMTPErrorResponse - Received SMTP error: 550 5.7.1 Unable to relay for email@example.com" Trying to setup Universal Messaging where this feature allows users to forward voice messages to an email address. I think the server need to set to accept email from the Mitel node and that attachments are allowed.
Experts, can you point me to where and how I can add the Mitel IP to be allowed on the server end? Thanks
