Spoofed email address despite Domain Keys enabled

Spoofed email address despite Domain Keys enabled

Hi there, 

I'm having problems with someone spoofing my email address in spite of having enabled Domain Keys. I've verified Domain Keys is set up correctly on my DNS record, and it's not in test mode. 

Here's an example of the message, with <myname>@<mydomain.com>:
