4 Steps to Decode a Failure to Deliver an Email
1. Display the Full Headers for the Email Message That Bounced
The process to do this will vary according to the email client that you use. With Google's Gmail client, you select the individual message, click the disclosure triangle on the top right of the message and select "Show original" from the menu.
2. Read the Headers from Bottom to Top
Headers are added to an email message at the top, so the topmost header lines will be the newest.
3. Examine the Top-most or Last Stage of the Email Delivery Process
A bounced email, or a failure to deliver notification, will uncover the cause for the bounce in the header. Look to the top of the headers for the last step that the mail servers attempted before the failure.
4. Convert a Numeric Delivery Failure Code to More Meaningful Data
The topmost header will contain a textual response that indicates precisely why the failure occurred, for example if the recipient address is unknown, or it will contain a numeric error code.You may need to convert the numeric code into a more meaningful response. A search engine will enable you to do this most effectively.
