I have Exchange 2013 running on Server 2012. It has started to reject quite a lot of inbound emails. I collect them with EFS on the same server and send them via SMTP. EFS shows that the emails are rejected - it doesn't say why. Some of these are regular text emails - nothing odd about them. If I send an email from my gmail it always works. Other emails work. In an ideal world I would like all emails to appear in my exchange mailbox - I will worry about filtering spam and virus content.
Why is Exchange rejecting the emails and is there a way to tell it to pass all emails through?
At request here is the header from a rejected email
