Displaying Full Original Headers for Problem Email Investigation

Full originalheaders provide information about the path the message took to get to you. Simple headers (To/From) can be forged so full headers are critical for the ITS staff members working to determine where the message originated from. Without them, there is almost nothing that can be done to investigate a problematic email. You will receive specific instructions when you report a problem e-mail as to where to send your message with full headers displayed.

Here's how to include full original headers using the following email packages:

M+Google Mail

  1. Log into U-M Google Mail.
  2. Display the message.
  3. Click the down arrow next to "Reply" at the top of the message.
