Get detailed information of a delivery report or read receipt.
[Visual Basic] Public Function GetReport( _ ) As MailReport
[C#] public MailReport GetReport( );
[C++] public: MailReport^ GetReport( );
[JScript] public function GetReport( ) : MailReport;
Return Value
Read Receipt
Some e-mail applications, such as Microsoft Office Outlook, employ a read-receipt tracking mechanism. A sender selects the receipt request option prior to sending the message. Upon opening the email, each recipient has the option of notifying the sender that the message was opened and read or deleted.
However, there is no guarantee that you will get a read-receipt. Some possible reason are that very few e-mail applications or services support read receipts, or simply because users disable the functionality. Those do support read-receipt aren't necessarily compatible with or capable of recognizing requests from a different e-mail service or application
Delivery Receipt and FailureReport
It is also called a DSN (delivery service notification), which is a request to the recipient’s email server to send you a notification about the delivery of an email you've just sent. The notification takes the form of an email, and will tell you if your delivery succeeded (Delivery Receipt), failed, got delayed (Failure Report).
Example
[Visual Basic, C#, C++/CLI] The following example demonstrates how to parse the delivery report with EAGetMail POP3 & IMAP4 .NET Component. To get the full samples of EAGetMail, please refer to Samples section.
