You have probably received an email from a sender you don't know. Maybe they claim to know you, but their email address doesn't tell you anything.

In any case, you want to know who is hiding behind this email address in order to know how to respond better. In this article, we will show how to trace an email address back to its owner.

Why trace an e-mail address?

Why Trace An Email Address

First of all, why bother to trace the IP address of the email?

These days, malicious emails are all too common. Scams, spam, malware and phishing emails are commonplace in the inbox. Finding the source of this email will give you a chance to find out who and where the email came from.

In other cases, you can trace the origin of an email to block a persistent source of spam or abusive content, allowing you to free your inbox of these.

Understanding Email Header Data

Before we dive into the email header to learn how to trace an email address back to its owner, we need to understand what data it contains.

En Head Mail Source 1

  • To: this is the sender of the email. However, do not rely on this as this information can be faked by spammers.
  • Reserve : Displays the exact date the email was sent.
  • Reply-To: this is the email address to which you send the reply.
  • Subject: Obviously the subject of the email.
  • Return-Path : This is an essential element that provides the email address to which the system will send its message. This is where unsent or bounced messages end up.
  • Received: the "Received" line lists each server the email passes through before reaching your inbox.
  • MIME-Version: MIME stands for Multipurpose Internet Mail Extensions and represents the email format standard currently in use.
  • Content type: lets the email client or browser know how to "read" the content of the email. It will probably be either UTF-8 and ISO-8859-1 character set.
  • SignaturesDomainKeys and DKIM : By associating the domain name with the email, DomainKeys and DKIM (DomainKeys Identified Mail) signatures help email services recognize and authenticate messages.
  • ARC-Authentication-Results: : ARC identifies email forwarders. It stands for Authenticated Receive Chain.
  • ARC-Message-Signature: validates email header information, much like DKIM does.
  • ARC Seal: Verifies the content of the authentication results and the message signature.
  • SPF received: The SPF or Sender Policy Framework is a part of email authentication which prevents forgery of sender address of emails.
  • X Google SMTP Source: indicates if the email used the Gmail SMTP server to forward.

Info: you don't need to understand what all these words mean to trace an email. But if you learn how to scan through the email header, you can quickly track down the sender of the email.

Find the original sender of an email

For trace the IP address of the sender of the original email , go to the second Received in the email header. Next to the first Received line is the IP address of the server that sent the email. Sometimes it appears like X-Originating-IP ou Original-IP.Gmail header

Find the IP address, then head to MX-Toolbox . Enter the IP address in the box, change the search type to reverse lookup using the drop-down menu, then press Enter.

The search results will display a variety of information related to the sending server.

However, the results do not always match.

Your success with tracing an email will vary depending on the sender's email provider. For example, if you try to locate an email sent from a Gmail account, you will only discover the location of the last Google server that processed your email, not the original sender's IP address. .
