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.
