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 Internet 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 Internet 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.
