Hi I dont know if you have experienced this problem whereby MX bounces messages after you restart your internet mail service with this message: our message did not reach some or all of the intended recipients. Subject: Sent: 3/4/04 8:46 PM The following recipient(s) could not be reached: 'u6eaZAKZk@xxxxxxxxxxx' on 3/4/04 8:53 PM Unable to deliver the message due to a communications failure The MTS-ID of the original message is: c=US;a= ;p=Interfresh;l=E_SERVER-040304184619Z-4 MSEXCH:IMS:Interfresh:EXCHANGE:E_SERVER 3902 (000B099C) Host Unknown All the messages in the queue are returned. I am puzzled. In this case I put a ficticious address for test purposes.
