Ok found the problem....
It seems the samples in FuzzyOCR won't fire because of the default
focr_autodisable_score
It might be worthwhile making a mention of that somewhere when
performing the tests.
"These eml files are sample spam emails to test your installation of
FuzzyOCR. As
suming you are using the default settings, the output you get should
match the o
utput listed here."
this is not the case with SA 3.1.7 at least since the rules push the
score over 10 for these files.
and presumably it's going to depend on the bayes database if that's
enabled
