Sorry, exhaustive training doesn't change anything in my case. Spamicity
value is still less than 0.52. Tuning robx/robs gives me strange results.
Some good letters become spammy after that. I think the algorithm has to
be changed somehow for small letters with a few words in the mesage body.
Otherwise, hammy headers always get greater value and never let the
spamicity score to be high enough.
