!Some mail clients and Internet Fax products currently on the market cannot receive this MDN format correctly.
!MDN vs. DSN
MDN = Message Disposition Notification DSN = Delivery Status Notification
MDN: you receive a confirmation that your message was received by the destination mail server.
DSN: you receive a confirmation that your message was opened by the person you sent it to (the recipient).
All systems involved in the communication must support MDN and DSN.
!When User Function 92, Return Receipt is set to ON, you will receive a notification when the recipient of your message opens it.
The recipient MUST HAVE a mail program that uses the Message Disposition Notification (MDN) standard.
Netscape Messenger, Eudora Pro, and the OKIFAX 5750/5950 and 5780/5980 Series Facsimile Machines support MDN.
!When User Function 98, Network Settings, Item 12, Delivery Service Notification (DSN) is set to ON, you will receive a notification when your message arrives at the recipient’s inbox on the mail server.
The recipient’s server must support the Delivery Service Notification (DSN) standard.
!Your machine always returns an MDN to anyone sending mail with an MDN request, regardless of the setting for User Function 92: Return Receipt.
