Analyze E-Mail Header and Find Email Address Source
Where Do I Get E-Mail Header?
In your email program. When viewing (reading) the message, please look for menu items which looks like "Show original", "Message properties", "Show all headers" or similar.
For example, in Gmail it is done as follows:
- Open the message to read
- In the top-right corner of the message click the down arrow (to display the menu of actions)
- Choose "Show original"
- In the newly opened window, copy the header text (header begining at the first line and ends as soon as you meet the first blank line).
Take into account. Do not copy and send the entire original message. In general, we do not mind, and our tool to cope with this task. But that's just not safe, as your letter will be sent over the network in plain text. The next problem could be if you reach the limit of data transmittion for this tool (your message just could be very large). Therefore, to analyze is better to send only the message header.
To let you better understand here is an example of the typical header:
