We were talking about this earlier, Lynne, and got me curious. I've noticed "On behalf of arjuna.harmonmediagroup.com" appearing in my client's sendmail generated messages. I saw that this was an Exim config thing. Is this to help get messages to the recipients without ending up in a spam box. Such as mail.hosteddomain.com coming from the sendmail on the server?

Would / should you change this behavior?
