When a mail server with DSN receives a message, it sends a delivery confirmation to the sender of the message.
Change this setting to OFF, if you are sending a message to a mail server that does not support DSN.
If you do not change this setting to OFF, the server may not be able to handle the message correctly and a communication error may occur.
Some servers can send mail to servers without DSN. In this case, no delivery notification will be sent.
The default setting is OFF.
! User Function 86, TEXT PRINT must be ON for your machine to receive and print delivery notifications.
