Can we get more info and stats on the correlation of spam and
fingerprinting of the OS?
The following figures are not representative as the mail traffic is
biased because of the user-base. About 60% of identified SMTP
sessions are from Windows hosts and 99% of the messages they sent
were identified as spam.
Now what happens to all the small businesses that use MS-Exchange to
send email?
Either you discriminate against them and lose business or else you
combine your fingerprinting with other heuristics to reduce its
effect. Some MS-Exchange hosts are behind non-Windows devices and
the OS won't be detected as Windows.
