Delivery Status Notifications (DSN)

Bounced mails (eg user unknown) return to the sender’s email address or to the return-path address (if specified).

In the event of a delay in the delivery of the messages, you will receive a warning after 30 minutes*, like this:

Subject:  
      Warning: could not send message for past 30 minutes  

Body:  
      **********************************************  
      **      THIS IS A WARNING MESSAGE ONLY      **  
      **  YOU DO NOT NEED TO RESEND YOUR MESSAGE  **  
      **********************************************  
      [...]  

The system will automatically retry for four hours*. If you do not receive further notifications, it means that the messsage has been successfully delivered. You can check the details within the logs (see the above mentioned examples).

After four hours* unsuccessfull retries, a definite error will be returned to the sender’s email address or to the return-path address (if specified), like this:

Subject:  
      Returned mail: see transcript for details  
Body:  
      The original message was received at ...  
      ----- The following addresses had permanent fatal errors -----  
      <recipient@yourcustomer.com>  
      ----- Transcript of session follows -----  
      Deferred: Connection timed out with yourcustomer.com.  
      Message could not be delivered for 4 hours  
      Message will be deleted from queue  
      [...]  

* = when sending bulk mailings:
delayed delivery status notifications are disabled,
the interval between the delivery attempts is increased (from ten to thirty minutes),
the maximum time of permanence in the queue is longer (from four to twenty-four hours)

Successful delivery notifications

On request, we can turn on the “delivery notification” for successfully delivered mails too. In this way, for each delivered message, the sender will receive the delivery receipt from the destination server. like the one below. This option is useful for those who need delivery receipts for each mail sent.

Subject: 
      Return receipt
Body:
      The original message was received at ...
      ----- The following addresses had successful delivery notifications -----
      <recipient@yourcustomer.com>  (successfully delivered to mailbox)
      ----- Transcript of session follows -----
      <recipient@yourcustomer.com>... Successfully delivered
      [...]

In rare cases (less than 1% of mails sent), the receipt is not released to the sender. This happens if the recipient has activated a special “privacy / noreceipts” option on his mailserver. This setting is generally not recommended as it also blocks the sending of standard non delivery notifications.
