What is the Mail Delivery Subsystem?

The Mail Delivery Subsystem is a set of protocols that allow email to be delivered. When a message fails to be delivered, a user will receive a bounced email that indicates which address the email came from and why it was returned. The owner of the message can try to fix the problem by contacting the recipient. A bounced email should tell the user the reason the message failed to be delivered. But, in most cases, there is no need to worry, because it is a normal process.

Generally, failed delivery is the result of invalid email addresses. When you create an email address, be sure to spell it correctly. Even a single misplaced letter can cause a message to be rejected. You may also receive bounced emails because the address has been closed or moved. It is important to know what these reasons are so that you can resolve the problem. Once you’ve resolved the issue, you can try the other methods of mail delivery.

One of the most common causes of failed delivery is an incorrect email address. This can be due to incorrect spelling or even a single letter. Another common reason is a non-functioning forwarding address. An email address can be invalid, because the Mailer Daemon isn’t configured to accept messages from it.

If you don’t know what’s causing your failed delivery, try checking your account settings.
