Backtracking E-mail Messages
Ask most people how they determine who sent them an email message and the response is almost universally, "By the From line." Unfortunately this symptomatic of the current confusion among internet users as to where particular messages come from and who is spreading spam and viruses. The "From" header is little more than a courtesy to the person receiving the message. People spreading spam and viruses are rarely courteous. In short, if there is any question about where a particular email message came from the safe bet is to assume the "From" header is forged.
So how do you determine where a message actually came from? You have to understand how email messages are put together in order to backtrack an email message. SMTP is a text based protocol for transferring messages across the internet. A series of headers are placed in front of the data portion of the message. By examining the headers you can usually backtrack a message to the source network, sometimes the source host. A more detailed essay on reading email headers can be found .
If you are using Outlook or Outlook Express you can view the headers by right clicking on the message and selecting properties or options.
Below are listed the headers of an actual spam message I received. I've changed my email address and the name of my server for obvious reasons. I've also double spaced the headers to make them more readable.

According to the From header this message is from Maricela Paulson at s359dyxxt@yahoo.com. I could just fire off a message to abuse@yahoo.com, but that would be waste of time. This message didn't come from yahoo's email service.
The header most likely to be useful in determining the actual source of an email message is the Received header. According to the top-most Received header this message was received from the host 12-218-172-108.client.mchsi.com with the ip address of 21.218.172.108 by my server mailhost.example.com. An important item to consider is at what point in the chain does the email system become untrusted?
Email security services will include blocking ransomware and emerging threats with the highest effectiveness and accuracy, stopping new and sophisticated threats such as ransomware, spear phishing, and business email compromise.

A honest MTA must report from where it receives the message. From the given message “asusus-4b96([58.88.21.177])”doesn't report from where it receive the message. since we assume the only originator is dishonest. so“asusus-4b96([58.88.21.177])” is the originator.
The Ip address that I got when I went to whatsmyip.com was 96.48.125.42, this is suppose to be my hackers address. After I got this address i started to search google for websites that would allow me to find my hackers location and address. The website I used was http://www.iptrackeronline.com/. This website is accurate in determining my isp provider which in this case is shaw and furthermore it is also accurate in determining the city and country in this case which was Surrey BC Canada. The only problem that it had was getting my address right it was a bit off.
Whose message is this (who is the source)? Who created or paid for it and why?
The Access Data’s FTK is a regular approved computerized analysis software that can aid in the decryption of passwords within a visceral amalgamate (Banday, 2011). This will help quickly analyze emails. This software backs several favorable automation like Credant, SafeBoot, EFS, and S/MIME to name a few (Banday, 2011). The EnCase forensic is another tool that would aid in an email extraction by imaging a drive and maintain the forensic evidence in a file configuration like LEF or E01 (Banday,
Mississippi History cannot be talked about without reference to the Mississippi River, cotton, or racism. All three played a major part in the formation of Mississippi history and its continuing development. The Mississippi River gave the state its name and plays a major role in the state’s transportation system and economy. Cotton was Mississippi’s largest cash crop during slavery and beyond and still places high on the state’s list of domestic products. Racism has been prevalent in Mississippi since before it became a state. It was at the root of slavery, sharecropping, and segregation.

In a reply, include the relevant parts of the original message for clarity, but keep the quotations to a minimum. Otherwise, simply attach the original message. Cite your information clearly and correctly, even if you are paraphrasing. When ending an email always use a signature because it identifies who you are and includes means of contacting you, but keep it short.

Email (electronic mail) was one of the biggest breakthroughs in communication when the internet was commercialized. With email, it became possible to send messages and letters across the world in a matter of seconds to the recipients address. Email was used as an alternative to conventional mail or snail' mail, as the term was introduced to describe its speed. As technology improved, it became possible to attach' documents, photographs and even sound clips or songs to emails which made mail by post redundant. Emails used packet switching software whereby the email was broken down into packets' and sent via the internet to the recipient.
