How to check email is original or not

How to check that Email is Fake original

There are many peoples who don't know which email is valid and which email is not.In this article I am going to show you how to check that email is valid or not.

First of all you need to learn how email works on internet.

 So Here The Sender i.e Mail User Agent 1 (MUA1) is sending a mail to Mail User Agent 2 (MUA2). So the sender will type the mail and click on send button and mail first send to Mail Transfer Agent (MTA)and then over the internet.And then another Mail Transfer Agent.Then MTA  send your mail on mail box and mail box send mail to Mail delivery Agent (MDA) and after all these steps mail reach to its destination.

That was the summery,how email travel over the Internet.

Now How to Send The Fake Mail.

To send fake mail We need to Bypass the abc@1server and 1server.com both and directly send an email over internet .

So for that we will use a .php script as php has a function mail(); which can send email to any one without the 1server.com and directly delivering the mail to 2server.in and then 2server.in will search for the xyz@2server.in in their own database and then the mail will be forwarded to xyz@2server.in and when the XYZ user login to their account they will see an email in their inbox which is from abc@1server.com.

<?php

$to                 = 'web123@demo.com' ;

$subject         = 'the subject ' ;

$message       = ' hello' ;

$headers        = 'from: web123@demo.com'    . "\r\n"   .

         'Reply-To: web123@demo.com'   . "\r\n"  .

         'X-Mailer:  PHP / '   .  phpversion();

mail($to,  $subject, $message,  $ headers);

?>

But actually the email is not sent by abc@server1.com to xyz@server2.in so it is a fake mail.

There are many websites who provide services of sending fake emails.

you just have to land on their page,fill form and send fake mail

Now How can you check When you receive such mail.

Step 1:- First of all open the mail.

Step 2:- Now Click on the downarrow near reply button and then click on show original button.

Now you have to check for the received from field on the page opened and see who has sent you the email , here billgates@microsoft.com is the sender so in the received from field check that there must be microsoft.comand not any other thing. this was fake mail as there is outgoing.hostingexample.com and so the mail is fake as there is no microsoftcompany.com here.

Remember:

Do not send fake mails for criminal activities.Your IP address  can be tracked and your criminal activities.

So please do not try to destroy any one's account.This post is only for educational purpose.

Remember that when you enter password in password field on any web browser then it will be save somewhere in back end.Its just a matter of time when hackers figure it out where your password place.

For the security reasons password field in all browsers is masked with “asterisks” which won’t allow any third person (even you) to read the original typed password.
