I heard an interesting story from a friend who was working in Mexico for
the past few months. Apparently in some Latin American countries,
uppercase legitimate person-to-person e-mail is common because it is
seen as a sign of respect. This apparently is due to historical
telegraph messages being in uppercase.
Perhaps this is the reason why so much spam going into the States is
uppercase despite it being a common sign to Americans of spam.
This might be a caution to us to avoid high scores on uppercase rules?
Our ham corpus likely does not have ordinary South American users to
test it properly.
