How to Check Email Origin: A Guide to Tracing Email Provenance
Checking email origin is the process of determining the true source of an email message. This involves examining the email’s headers, which contain technical information about the email’s transmission path. By analyzing the headers, you can identify the IP address of the server that sent the email, as well as the path the email took through various servers before reaching your inbox.
Checking email origin is important for several reasons. First, it can help you to identify spam and phishing emails. Spam emails are often sent from spoofed addresses, which can make them appear to come from a legitimate source. Phishing emails are designed to trick you into giving up your personal information, such as your password or credit card number. By checking the email origin, you can verify that the email is actually coming from the person or organization it claims to be from.
Second, checking email origin can help you to track down the source of unwanted emails. If you are receiving unwanted emails from a particular address, you can use the email origin information to identify the server that is sending the emails. You can then contact the server’s administrator and request that they take action to stop the unwanted emails.
Checking email origin is a relatively simple process. There are a number of online tools that can help you to check the origin of an email. You can also use the built-in tools in your email client to view the email headers.
1. Sender’s email address
The sender’s email address is often the first thing that people look at when trying to determine the legitimacy of an email. However, it is important to be aware that email addresses can be spoofed, which means that they can be made to look like they are from someone else. This can make it difficult to determine the true origin of an email and can lead to people being scammed or phished.

Spoofing
Spoofing is a technique that allows someone to the sender’s email address in an email message. This can be done using a variety of methods, including:- Using a fake email address
- Using a legitimate email address that has been hacked
- Using a service that allows people to send emails from any email address
-
Why spoofing is a problem
Spoofing can be a problem for a number of reasons. First, it can make it difficult to determine the true origin of an email. This can lead to people being scammed or phished. Second, spoofing can damage the reputation of legitimate businesses. If someone receives a spoofed email that appears to be from a legitimate business, they may lose trust in that business. -
How to check for spoofing
There are a number of ways to check for spoofing. One way is to look at the sender’s email address. If the email address is not from a legitimate domain, it is likely that the email is spoofed. Another way to check for spoofing is to look at the email headers. The email headers will contain information about the email’s origin, including the IP address of the server that sent the email. If the IP address is not from a legitimate server, it is likely that the email is spoofed. -
What to do if you receive a spoofed email
If you receive a spoofed email, the best thing to do is to delete it. Do not click on any links in the email or open any attachments. You should also report the email to your email provider.
By being aware of spoofing and taking steps to check for it, you can help to protect yourself from being scammed or phished.
2. Domain name
The domain name is an important part of an email address. It is the part of the email address that comes after the “@” symbol. The domain name tells you which organization or company the email address belongs to. For example, the domain name in the email address “john.doe@example.com” is “example.com“.
It is important to check that the domain name is legitimate because it can help you to determine whether or not an email is spam. Spam emails often have fake domain names that do not match the sender’s name. For example, a spam email might have a domain name like “example.ru” or “example.cn“. These domain names look similar to legitimate domain names like “example.com“, but they are actually fake.
You can check the legitimacy of a domain name by using a WHOIS lookup tool. WHOIS is a database that contains information about all registered domain names. When you perform a WHOIS lookup, you can see who owns the domain name and when it was registered.
It is also important to check that the domain name matches the sender’s name. This is because some spammers will use a legitimate domain name, but they will send the email from a different address. For example, a spammer might send an email from the address “john.doe@example.com“, but the domain name might actually be “example.ru“.
If you are not sure whether or not an email is legitimate, you should check the domain name and the sender’s name. If the domain name does not match the sender’s name, or if the domain name is fake, you should delete the email.
3. IP address
The IP address is an important part of an email header because it can help you to determine the true origin of an email. By using a WHOIS lookup tool, you can identify the owner of the IP address and determine whether it is associated with spam or phishing.
-
Identifying the source of an email
The IP address can help you to identify the source of an email, even if the sender’s email address has been spoofed. By performing a WHOIS lookup on the IP address, you can see who owns the IP address and where it is located. -
Determining whether an email is spam or phishing
Spam and phishing emails often come from IP addresses that are associated with spam or phishing. By checking the IP address of an email, you can determine whether it is likely to be spam or phishing. -
Taking action against spam and phishing
If you receive an email from an IP address that is associated with spam or phishing, you can take action to protect yourself. You can report the email to your email provider and/or block the IP address.
By understanding the IP address and how to use it to check email origin, you can help to protect yourself from spam and phishing.
4. Email headers
Email headers are an important part of email forensics. They contain a wealth of technical information about the email’s transmission path, including the following:
- The sender’s email address
- The recipient’s email address
- The date and time the email was sent
- The subject of the email
- The IP address of the server that sent the email
- The IP addresses of the servers that the email passed through
- The date and time the email was received by each server
By analyzing the email headers, you can identify the servers that the email passed through and determine whether it was intercepted or altered. This information can be used to track down the source of spam or phishing emails and to investigate email security breaches.
Here is an example of how email headers can be used to track down the source of a spam email:
Received: from mail.example.com (mail.example.com [192.168.1.1])by mail.example.org (Postfix) with ESMTP id 0A79218423for ; Thu, 12 Apr 2018 16:04:33 -0400 (EDT)Received: from mail.example.net (mail.example.net [192.168.1.2])by mail.example.com (Postfix) with ESMTP id 45A9218422for ; Thu, 12 Apr 2018 16:04:32 -0400 (EDT)Received: from mail.example.ru (mail.example.ru [192.168.1.3])by mail.example.net (Postfix) with ESMTP id 36A8218421for ; Thu, 12 Apr 2018 16:04:31 -0400 (EDT)Received: from mail.example.cn (mail.example.cn [192.168.1.4])by mail.example.ru (Postfix) with ESMTP id 27A7218420for ; Thu, 12 Apr 2018 16:04:30 -0400 (EDT)
In this example, the spam email was sent from the IP address 192.168.1.4. This IP address is located in China. The email was then forwarded to the IP address 192.168.1.3, which is located in Russia. The email was then forwarded to the IP address 192.168.1.2, which is located in the United States. The email was then forwarded to the IP address 192.168.1.1, which is also located in the United States.
By analyzing the email headers, we can see that the spam email was sent from China and that it passed through Russia and the United States before it reached the recipient’s inbox. This information can be used to track down the source of the spam email and to take action to stop the spammer.
