Mail Delivery Rejected
Posted on 2010-11-18
Hi... I have a user within our network that is unable to receive mail from paticular client (error message below). I can receive mail from that client without a problem. Our mail is directed through a spam filter offsite but the message never reaches our exchange server. Several months ago our IP address changed and it took a little while for our records to be updated but that does not seem to be an issue for anyone else. I did verify that the sender is on our white list. I would have thought that if he could get through to my email that he would be able to send to all of us. Maybe the senders email is somehow still using the old ip address????
I appreciate your help!
