Hi,
to read this in other words: while certain analysts (and definitlely microsoft
marketing)
claim that about 50 % of all servers is running windows, these figures tend to
say that
real mail servers (those that deliver the ham part of mail) rarely ever run XP
but that this OS is the best candidate for creating a spam zombie

p0f OS guess ham : spam
-----------------------------
Windows-XP 0.7 % : 99.3 %
Windows-2000 5.8 % : 94.2 %
UNKNOWN 16.5 % : 83.5 %
Linux 58.8 % : 41.2 %
Unix 80.3 % : 19.7 %
(Unix+Linux 66.5 % : 33.5 %)
Only 0.7% of all mail coming from Windows-XP hosts is ham!!!
It is an ideal information to contribute two or three score points.
