I am running exchange 2013. We have a website where we are advertising a live streaming event. People can then enter their email address and their friends email adders to send an evite. When the server sends the email, the email go to the name specified and the from is the person who entered their email address. Looks like somewhere there's a problem, as people, I think everyone are getting their emails returned back to them. Here's the error message, I'm trying to figure out if it's my problem, or is it yahoo's problem or who's ever email provider they are using.
I changed my domain name to @mydomain.org, but can someone validate if this is my problem with exchange, or yahoo's issue?
