Question
find out at least ten pieces of spam mail from any account, whether it be home, work, school, or something else. using e-mail header and any website that might provide information attempt to trace the spam mail back to its original source.
you will need to following materials:
1. collect the e-mails and view the email header information into your program.
2. find the received field in the headers and write down as many DNS names or IP addresses as you can. also look for common details in the header element of the different messages, such as the same email servers and spammers.
Explanation / Answer
In order to view the headers you'll need to load the email from the server, how this happens varies based on whether you're using exchange, imap or pop but the bottom line is by the time you're looking at the headers the email is already on your PC. Luckily for you however a virus/malware/trojan cannot inject your PC via email, unless you have your outlook setup to allow external HTML and you never apply updates. To get around this, spammers and those with malicious intent will either include an attachment or website link that they try to trick you into opening. The email itself however is completely harmless.

An email consists of three vital components: the envelope, the header(s), and the body of the message. The envelope is something that an email user will never see since it is part of the internal process by which an email is routed. The body is the part that we always see as it is the actual content of the message contained in the email. The header(s), the third component of an email, is perhaps a little more difficult to explain, though it is arguably the most interesting part of an email.
To really understand what an email header is, you must see one. Here is an example of a full email header*:
email headers should always be read from bottom to top.
Fortunately, most of this information is hidden inside the email with only the most relevant or mandatory headers appearing to the user. Those headers that we most often see and recognize are bolded in the above example.
headers also provide routing information
email headers also provide information on the route an email takes as it is transferred from one computer to another. As mentioned earlier, mail transfer agents (MTA) facilitate email transfers. When an email is sent from one computer to another it travels through a MTA. Each time an email is sent or forwarded by the MTA, it is stamped with a date, time and recipient. This is why some emails, if they have had several destinations, may have several RECEIVED headers: there have been multiple recipients since the origination of the email. In a way it is much like the same way the post office would route a letter: every time the letter passes through a post office on its route, or if it is forwarded on, it will receive a stamp. In this case the stamp is an email header.
