Displaying Email Headers


The full Internet email headers include useful and sometimes necessary diagnostic information. Typical reasons include blocking spammers (unsolicited junk email), problems with delivery or receipt of a particular message, and certain identity troubleshooting issues that involve fake "from" addresses. Displaying headers in some email programs is an easy task. However, both Outlook and Outlook Express are more difficult in this regard.
