Most people are familiar with mail headers such as From:, To:, Subject: etc. but there are many more which most people never see. Quite often we need to see the full internet mail headers from an e-mail that is causing problems. This article explains how to get hold of them in some of the more common e-mail clients.
When viewing a message, click Options → Show Headers
. The headers will show in a pop-up box - if you use an Internet browser like Firefox or Opera, you will be able to select and copy the text of this box.
When viewing a message, click the link Full headers
. You should see the full internet headers in place of the usual display of To, From, Subject, Date.
On the main menu bar, go to View → Headers → All
and then select the relevant e-mail message. You should see the full internet headers in place of the usual display of Subject, From, Date, To.
Double click the message to open it in a new window. On the menu bar of this window click View → Options
and in the dialog box that comes up you'll see the mail headers listed in the Internet Headers
text box.
When viewing your list of messages, right-click on the desired message and select View All Headers and Message
.
Alternatively once the message is open, you can right-click into the message itself and select View All Headers and Message
. The full headers and message will display in place of the formatted message.
