SendAsyncMDN Method
Sends the MDNReceipt to the RemoteURL specified.
Syntax
int SendAsyncMDN(const QString& qsRemoteURL, const QByteArray& qbaMDNReceipt, const QString& qsMDNReceiptHeaders);
Remarks
This method sends the asynchronous MDNReceipt to the RemoteURL specified. It need not be invoked if the prior call to SendResponse was successful. The RemoteURL, MDNReceipt, and MDNReceiptHeaders parameters should be the ones that were retrieved from ReceiptDeliveryOption and MDNReceipt's Content and Headers properties respectively.
If the RemoteURL requires SMTP transfer, the appropriate SMTP settings should be set using Config.
Error Handling
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
