Property Value

Type: String
A string containing the original envelope ID taken from "Original-Envelope-Id" DSN field, or a null reference (Nothing in Visual Basic) if no such field contained in the DSN.

This field contains an "envelope identifier" which uniquely identifies the transaction during which the message was submitted by sender. When sending the original e-mail message, you can specify this ID using Smtp.DeliveryNotification.TrackingID property (the sending mail server, however, must support DSN extension).

In this example, DSN field is:
Original-Envelope-Id: A406980DD7D140DCAD796DDCE62EF673.MAI@afterlogic.com
The return value is marked bold.
