Would it be worthwhile those of us who've received infected mails PM'ing you the senders details.
No. The From:-field is forged.
The only way these emails would useful for tracking purposes would be to get full headers of the email messages.
The last "Received: from" entry has the name and IP of the sending system. If this is a localhost or LAN ip, then you need to walk the received chain upwards till you find the external IP of the sending host.
