Setup Mail (TX)
You can set the Notification option in the Setup Mail TX option to either ON or OFF. When switched to ON
an additional field of information is sent with the image data. This field is named MDN.
MDN
Mail Disposition Notification - This field requests the status of the I-Fax / E-mail message after delivery
through the SMTP (Send Mail Transfer Protocol) transport system. Once the message has arrived at the
Receiving station this data is used when the machine or user reads or prints the received I-Fax or E-mail. For
example, if the message is opened for reading or is printed the receiving station sends back a notification to
the original sending machine or user.
The receiving station must support the MDN field in order to be able to send a notification report, otherwise
the request will be ignored.
Setup Mail (RX)
There are three possible settings for this option ON/MDN/OFF.
Receive Notification “ON”
When switched to “ON” a fixed message is sent back to the sending station to indicate successful reception
and processing of the message. These fixed messages depend on the operation requested by the sending
station.
Report messages consist of
SUCCESS : Received From
Receive Notification “MDN”
When switched to “MDN” a report as described above is sent back to the sending station if the originating
station sent the “MDN” field to request confirmation.
Receive Notification “OFF”
OFF - Switches all forms of receive notification OFF, no messages are send back to the sending station
regardless of the request.
Error mail
If there is a mail delivery error while sending an Internet Fax, the mail server will send an error message back
to the machine and the error message will be printed. If there is an error while receiving mail, an error
message will be printed (Example: “The message being sent to the machine was not in a TIFF-F format.”).
