Identifying where e-mail originates

You will need to view the full e-mail headers to identify where the e-mail originated. The full e-mail header also needs to be included in your complaint. 

 

 

 

 

 

Once you are viewing the full header, look for lines that begin with “Received: from”. The Received: from lines are in chronological order, with the most recent mail server listed first. The last Received: from line (closest to the Date: information) identifies the originating computer. Below is the full e-mail header of a piece of spam “phishing” for information.

The originating Received: from line is:

Received: from paypal.com (matrix08.matrixvd.com [80.97.37.138] (may be forged)) by av2.und.nodak.edu (portions deleted). Let’s take a look at this line.

 

 

Now that you have identified the originating computer (host) you may send a complaint to either postmaster or abuse at the domain portion of the hostname. In this example, the domain is matrixvd.com; the abuse address would be abuse@matrixvd.com. Note, the postmaster or abuse addresses aren’t guaranteed to work but are a standard addresses used for such purposes. Also, keep in mind that you may be receiving the spam as the result of a virus-infected computer and not as a direct assault against you, use your complaint as a chance to alert the originating site to the problem and request their assistance in stopping the spam.
