In this example the "Sender" located at sender@exampleuniversity.edu want to send an email to "Receiver" located at receiver@exampleisp.com. The sender composes his email at his workstation in the university's computer lab (lab.exampleuniversity.edu). Once completed the email message is passed to the university's mail server called mail.exampleuniversity.com. The mail server seeing that it has a message for receiver@exampleisp.com, contacts someisp.com mail server and delivers the email to it. The email is stored on someisp.com server until Receiver logs on to check his/her inbox.

In this example, four headers will be added to the email message. This first header is generated by email client on lab.exampleuniversity.edu when forwarding it to the mail server at mail.exampleuniversity.edu.

The following header is added when mail.exampleuniversity.edu transmits the message to mail.exampleisp.com.



The following header is added when mail.exampleisp.com stores the message on the server for Reciever.



The following header is added when Reciever downloads the email from home machine called reciever.local.




3) Tracking The Orginal Sender

The easiest way for finding the original sender is by looking for the X-Originating-IP header, this header is important since it tells you the IP Address of the computer that had sent the email. If you can not find the X-Originating-IP header then you will have to sift through the Received headers to find the sender's ip.



Once the email sender's ip is found go to http://www.arin.net/ to begin a search.


Now click on the "NET-24-16-0-0-1" link.


Scroll down the page untill you find the OrgAbuseEmail field.



Remember to include all the headers of the email along with an attached copy when filling a complaint.
