to see who is REALLY sending the email or the post etc....
Many people will pretend in yahoo behind a number of different alias's and this is how you can unmask and reveal them quickly...
First go to your yahoo mailbox and CLICK ON OPTIONS
THEN Look for GENERAL PREFERENCES in blue letters..
Then look for MESSAGES and select the SHOW ALL HEADERS...
That's it your done. Now if you receive an email in yahoo it will show the entire trace route of that email back to the originating I.P.
Enjoy! P>S> You can turn it off and on at will to examine letters at will. If you leave it on all the time you must do a lot of scrolling on all your email to read past the headers as they can be lengthy at times...
