Email spoofing is the creation of email messages with a forged sender address – something which is simple to do because the core protocols do no authentication. Spam and phishing emails typically use such spoofing to mislead the recipient about the origin of the message.
You might have watched your email account when it filters your mails automatically into spam or the inbox. Have you ever wondered how does this all work? well one obvious methodology is that the email app/service scans for any malicious software in that mail and keeps it aloof. The other way is that it scans the identity of the person from where the email is coming from to this particular email address, like if it’s coming from an invalid server, IP address, phishing page, or through any other illegal means, the email service will automatically detect the identity of the sender and filter it as spam. As a human how can we understand whether a particular mail is fake or a real one? this tutorial is all about it. Email spoofing can be very dangerous at times as an hacker could use anyone’s identity or email address to send unlimited emails to as many people as he can without revealing his real identity. Though it’s such a big deal you can very easily verify whether a mail you received is fake or a real one from a built-in option (i.e. by clicking on ‘Show original’ option on any particular mail). Today we’ll learn how hackers work this out and how we can save ourselves from this problem.
