Hello Ever since I installed Exchange 5.5 sp4, my server can longer send NDRs. Whenever a message reaches the server with a bad address, and the server tries to send back an NDR, I get the following error message: "The following recipients did not receive the attached mail. Reasons are listed with each recipient: <originator> originator MSEXCH:IMS:ANZIMA S.A.L.:ANZIMA:YASMINA 3550 (000B09AA) 550 relaying mail to [originator domain] is not allowed."
My server is Yasmina, and my organization/site is Anzima. For outbound mail, I set Exchange to forward all messages to my ISP SMTP server, because if I use DNS, a lot of messages fail to be delivered (I have a dial-up connection). Thank you for your help.
