SYMPTOMS

If a Collaboration Data Objects (CDO 1.21) application receives a message from a POP3 user in the site and replies to or forwards the message to a non-existent Internet recipient, a non-delivery report (NDR) may be sent to the POP3 user. In addition, if a CDO (1.21) application replies to a message from an Internet message that includes a "Reply-To" field, CDO (1.21) copies the "Reply-To" field to the reply message.
