How to View Email Headers

How to View Email Headers

View, Copy and Paste Email Headers for Email Trace

If you want to conduct a reverse email lookup search or trace an email address to locate the name and address of the person that sent it, you will need to be able to provide the full email header and the email address.

The instructions below should help you view and copy (extract) headers from many of the popular email programs. Once you are able to view and copy the full email header you can paste them into any online form or document you want.

Hotmail:
Log into Hotmail.
Click on “Options” tab on the top navigation bar.
Click on the “Mail” link on the navigation bar on the left.
Click on the “Mail Display Settings” link.
Change the “Message Headers” option to “Full”.
Click the “OK” button.

Yahoo Mail:
Log into your Yahoo! Mail account.
Click the “Options” link on the navigation bar.
Click the “General Preferences” link.
Go to the paragraph titled Messages and Locate the Show Headers heading and select “All.”
Click the “Save” button to put your new settings into effect.
Once this setting is saved, go back and open your email and you should view the headers.

AOL Mail:
If the email is sent from anywhere OTHER then AOL, and you are receiving it in AOL, then open the email you want to trace, or have your client open the email, and look for the link Details. This link is usually just below the To:email in the email message. If the email is sent from an AOL user to another AOL user then our Reverse AOL Screenname search can get you the sender’s information.

Gmail:
Log into your Gmail Account
Open the Email whose headers you want to view
Click on the more options link in the message next to the date of the email.
If the link says hide options then do not worry you have already clicked on the more options link.
Now click the link called show original.
This will bring up a new window with headers and the body of the message.

NOTE: With Viruses, Worms and Trojans being spread via email, many users now work with the preview screen in Outlook Express turned off. Viewing email in the preview screen is no different than opening the message. If the email has malicious content, it may execute in the preview screen.

Note: Using the cut and paste to the web form method is the only option available to Eudora users.

Eudora for the Mac:
Open the email and click the button on the upper left hand corner of the message.
This shows the extended headers. Select the whole message including headers and paste.

Eudora for the PC:
There are 2 slightly different methods depending on whether the mail contains HTML or not.

To prepare for HTML email you should turn off the use of Microsoft’s HTML viewer.
Click Tools, then Options, then Viewing Mail.
Uncheck the box labeled “Use Microsoft’s viewer.”

How to know if it’s HTML mail:
Open the email and look near the bottom of the headers (see below for revealing headers) for a line like the following:
Content-Type: text/html
You can frequently spot HTML email because it does not look like plain text. It usually has some font effects (like bold or underlines), some graphics or pictures. It’s not always true so you have to take a quick look at the headers.

Eudora for the PC – non-HTML mail:
Double click on the subject line to open the email.
Click the button to reveal the headers.
Place your cursor anywhere in the body of the email and select the entire message (Edit/Select All or Ctrl-A)
Copy the entire email (right click and click copy OR Ctrl/C OR Edit/Copy)
Paste (right click/paste or Ctrl/V).

Eudora for the PC – HTML mail:
Open the email and click the button to reveal the headers.
Highlight the headers only. Copy and paste the headers.
Hit enter twice after the pasted headers to force a blank line after the headers.
Back in Eudora window, place your cursor anywhere in the body of the message and right click and click “view source”. A new window will open.
In the new window, select all (as above) and copy the contents of the new window.
