I receive the folowing error when sending an email to firstname.lastname@example.org:
<exchangeservername.domain #5.5.0 smtp; 550 not local host domain.com, not a gateway>
I am able successfully send if i send the same email from a POP3 account configured on my machine. So i am thinking the issues resides at my exchange server. But i can think of any configuration on my Exchange server that would be the culprit. I have specifically allowed relay from any host on my network so i dont think relaying is the issue. Even so, i am directly connected to the exchange server so relaying shouldnt even be relevant. Any one have an idea?
