In Outlook Express or Entourage, how do I display and send the full headers of an email message?

To mail the full headers of an email message you have received, you must first display the headers, and then insert them into the body of an email message.

Displaying full headers

• In Outlook Express for Windows:
  
  
  1. Right-click the message, and then select Properties. (If you have the message open, from the File menu, select Properties.)
  2. Click the Details tab. This will display the full headers of the message.
  
  
• In Entourage for Mac OS X, open the message in a separate window, and from the Message (Entourage 2008) or View (earlier versions) menu, select Internet headers.

Inserting headers into a message

To insert the headers into an email message:

1. Select all the headers by clicking and dragging the cursor from the top left corner to the bottom right corner of the header text.
   
   
2. Press Ctrl-c in Windows or Cmd-c in Mac OS X to copy the headers to the Clipboard.
   
   
3. Create a new email message. Click in its main text window, and then press Ctrl-v in Windows or Cmd-v in Mac OS X to paste the headers.
