Finding the mailheader

If you receive mail containing threats, phishing or other security related issues, you should always contact IT support. They will ask you for something called a mail header. An email message internet header provides a list of technical details about the message, such as who sent it, the software used to compose it, and the email servers that it passed through on its way to the recipient. Most of the time, only an administrator will need to view internet headers for a message.This is information key to track the sender of the mail. Perform the following steps to find the mail header.

You need access to the " original email " . If it isn't you who received the mail the easiest way is to visit the person who received the email. Do NOT forward the original mail since that will destroy the original header.
Log into Gmail, and open the specific mail .
Select "Show Original"

Now copy the header code and send in a ticket to support.
