Show Full headers in Mac Mail

In Mac Mail, the Headers are disabled by default.
To show the headers in Mac Mail, simply select a message you want tyo see the headers for, and in your menu go to 'view > message > show long headers'.
You will now see the headers appear for this message.
To undo this, just repeat the action (and select standard headers)

Its as simple as that.


or you can always use a hammer...
