Emails are very important part of our communication system
We think that we know everything about emails

we know how to compose email , how to attach a file , how to send it to others ,How to receive emails from others and many other things.This is all we know about emails.But this is not end of it .When you receive or send emails many other things are sent with it.
At this time when Email is progressively used for business and for many purposes, not to mention it is being used for phishing and other malicious intentions. It is of utmost priority to understand the other "messages" besides what has been sent or received by you.
Every email comes with a “Header” which is one part of an e-mail structure; call it DNA of the mail. It carries the basic fundamental information such as from whom the email comes, to whom it is addressed, date/time it was sent and the subject of the email. It is similar to an electronic postSeptemberk. Moreover, it also carries other detailed information which we usually don’t see.
This basic information comes in all brief/basic headers that most email programs automatically shows. This detail technical information can be viewed in a full header. All email programs can be set to show only brief header or full header and it is up to the users to set the program whether to view only “brief header” or “full header”.
Full header carries the information of the mail server’s name that the email passed through on its way to the recipient, and sender's IP address and even the name of the email program and its version used.
Knowledge of this information is essential for analysis and investigation purposes on cases involving email abuse, spamming, harassment, forgeries and mail-bombing. It is worth mentioning, understanding of this tool would definitely help people to counter these attacks, and save themselves from unwarranted consequences. Well, this information could not be found in a brief header.
Here we will take the case of Google mail and Yahoo mail to find out the full header.
Google Mail.
Using your id/password, login to Gmail. Open the mail for which you wish to find the full header of the sender. Click on the inverted triangle placed just next to Reply.

Also importantly, there are times when you might find multiple Received: from entries, in that case, please select the last one as the valid choice.

When you receive an email, you receive more than just the message. The email comes with headers that carry important information that can tell where the email was sent from and possibly who sent it. For that, you would need to find the IP address of the sender. The Tutorial below can help you find the IP address of the sender. Note that this will not work if the sender uses anonymous proxy servers.


First of all, the IP address is generally found in the headers enclosed between square brackets, for instance, [129.130.1.1]

* Open the mail.
* To display the email headers,

* Look for Received: from followed by the IP address between square brackets [ ].


Received: from [69.138.30.1] by web4587.mail.***.yahoo.com

* Track the IP address of the sender




Finding IP address in Yahoo! Mail

* Log into your Yahoo! mail with your username and password.

Or if you want to manually find the IP address, proceed to 6.

* Look for Received: from followed by the IP address between square brackets [ ]. Here, it is 202.65.138.109.

That is be the IP address of the sender.


If there are many instances of Received: from with the IP address, select the IP address in the last pattern. If there are no instances of Received: from with the IP address, select the first IP address in X-Originating-IP.

* Track the IP addess of sender




Finding IP address in Hotmail

* Click on Ok button
* Go back to the mails and open that mail

* You should see the email headers now.
* Manually find the IP address, proceed to 7.
* If you find a header with X-Originating-IP: followed by an IP address, that is the senders IP address


Hotmail headers
In this case the IP address of the sender is [68.34.60.59].

* If you find a header with Received: from followed by a Gmail proxy like this


Hotmail headers
Look for Received: from followed by IP address within square brackets[]



In this case, the IP address of the sender is [69.140.7.58].

* Or else if you have headers like this


Hotmail headers
