While sending an E-mail it is associated in two packages. The first one is, Envelope Sender and the other is, From: address. The E-mail sends and respond in the same way as of postal mail delivering method. The difference is only of Physical and Internet world. The Postal mail delivers mails in physical form, but the E-mail acts via Virtual world. Like in the example:

  • We click send in your e-mail client and wait for mail server to pick up.
  • Our e-mail gets picked up by the e-mail server set in our outgoing mail server settings.
  • Then our e-mail tries to deliver from the e-mail server, to our friends remote e-mail server.
  • At final our e-mail is delivered into our friend's e-mail Inbox.

1. Envelope Sender:

Envelope sender is the E-mail package in which computer should respond. If the mail doesn’t carry appropriate E-mail address or having some issue in receiver’s Mail server it would return back to us showing Non Delivery Report(NDR) with Non Delivery Notification (NDN). It basically depends on two factors i.e Mail server and Destination of our E-mail server. The mail which is returned back is called as Bounce mail or Non Delivered Report.




Bounce mail is the mail which we receive on our E-mail Account because of undelivered mail, due to inappropriate Address entered or Temporary delivery problem with the E-mail server showing the notification as shown in an image given below:

  • This mail showing the Non Delivery Report, and is sent either by our mail server, or the destination of the mail server of our E-mail. Bounce back messages are a method which help us to know, that something has happened to disrupt our email delivery. Mail servers uses Mail Transfer Agent (MTA) to handle the deliveries for the server. If we typed our friend's email address incorrect or due to temporary delivery problem with their mail server, then the remote MTA will send a bounce back message to our Email error comprising of message or error code and explaining the reason for undelivered mail.
