Most of these worms are not complex enough to spoof the senders IP as well. Although if you do try and trace it the likelihood is that you will stumble across an IP address that is assigned to an ISP and therefore will never really find the location of the email origin.

If the email you received from admin@<your domain> and came through the gateway then I am extremely confident that the worm has not infected your internal network.
