The spam has only been trickling in recently, for better or worse, so I just have these two overseas educational institutions to share from the end of last year:

Heriot-Watt University
Riccarton
Edinburgh EH14 4AS
United Kingdom

spammed us on Tuesday, 29 December 2009 - 11:58am via IP 137.195.176.11

National Chung Cheng University
Chia-Yi Taiwan

spammed us on Wednesday, 30 December 2009 - 10:59pm via IP 140.130.17.72

I don't know what the vacation schedules are in those parts of the world, but I would not be at all surprised to find that it was not student machines that were the source of these spam.
