This is a quick step-by-step guide to viewing the headers of an e-mail in Gmail. You may be asked to provide an e-mail header, by a member of the 34SP.com Technical Support team. We use the information in the header to troubleshoot mail delivery problems.
When an e-mail is created, it is made up of several components. One of those components in the 'message body', which is the content of the e-mail. Another part is called the 'header', which is normally hidden. The job of an e-mail header is to provide a detailed log of the network path taken by the e-mail, between the mail sender and the mail receiver.
