Avii, If you want to track the source of an email, the most important thing is to have a mail reader that can show you the full headers of an email in question. If you use yahoo or gmail, you can see the full header of the email. In the header, check the section "Received" which should give you the rough idea from where the email was sent. If you want to track the emails you sent to others, try readnotify. http://www.readnotify.com/ It's free and you can even track when your email was opened, where it was forwarded to.
