Hello Thomas,

IMO, yes, you should feed it some ham, but don't worry about keeping the
ratio even or close.  I'd suggest feeding it some ham that has positive
scores from time to time, say one ham for every 20-30 spam.  That ratio
seems to be sufficient for me -- Bayes is doing a wonderful job here.
