Few people in the world enjoy receiving unwanted email. Whether it's annoying spam of any variety or something more sinister, sometimes it's only natural to want to know where those unknown emails are coming from. However, if you want to learn more about a strange email address, you might not know where to begin. One place to start is by looking into the email headers of the message in question. Email headers are computer code attached to emails that tell computers where the message is coming from and where it's going. Here's how to implement Yahoo mail to find and use email headers to research unknown emails.
Finding email headers with Yahoo mail is easy. If you're using the New Yahoo Mail, simply view the message you want to open, and look for the words "Compact Header." By clicking on the down facing arrow just to the right of these words, a menu will pop up allowing you to choose "Full Headers." The email headers you are looking will pop up in a new window. If you're using the Yahoo Mail Classic, you can still find email headers, but it requires a few more steps. Choose the "Options" link for the menu bar, and then choose "General Preferences." Find the paragraph entitled "Messages," then locate the "Show Headers" heading and choose "All." Now, go back to your inbox and view the message you're interested in learning about. The full email headers should now be visible.
Finding the email headers is only the first step. Now you have to find out what they mean. Email headers can be tough to decipher because they are meant to be read by computers, not people. If you're trying to figure out email headers, the first thing you should look for is the phrase "Received: from." This phrase occurs every time the message is sent from one computer to another. The first time the phrase was written is actually the last one visible in the headers. Find the "Received: from" closest to the bottom of the headers, and look closely at that line. Next to "Received: from" there's usually a multi-digit number separated with periods. This is the IP address of the computer that originated the message. IP addresses are Internet identification codes that help computers find each other. You can use this IP address to learn more about the computer that sent the message, and possibly the person behind it.
Of course Yahoo email headers aren't the only way to find out more about a mystery message. If you need to find out who owns a Yahoo email address, you can use a reverse email search. Reverse email searches are services that provide information about unknown email addresses quickly and easily. No matter which method you choose, now you should have a better idea what resources are available to you on the Internet.
