General mail delivery question

[Edwin Minneboo]

Hi all,

 
I wonder how and why mail is delivered in the following case:

 

I own a domain, let's say example.com. In this domain mail for user
w...@example.com is delivered to e...@example.com.

Now I find mail for To: wilma.vivi...@nwu.ac.za Delivered-To: e...@example.com

 

As I don't understand the routing of this mail, and where the
w...@example.com come from I ask you to shine a led on this.

I do understand it is obvious spam, and so rated right with DSPAM, but I
really wonder why it is actually delivered.

 

Thanks in advanced for time and energy to answer.

 

Grtz Ed
