Answer 1

I have the same problem.
It seems that the MS Exchange server does not allow relaying, which means that emails from an external source (like a webserver) are not allowed to be sent.
This is supposed to help: http://technet.microsoft.com/en-us/library/dn554323(v=exchg.150).aspx
I set it up the way it's described, but it still did not resolve my problem. I'm also unsure how to integrate the MX-Server into my web-application. Using it as Server-Adress in the Zend_Mail_Transport_Smtp gave me the same error as before. Maybe someone else can clarify that with the additional information.
