Simonthe cached here means it's already seen it and scored it 'low'. Try
removing the spamassassin cache and restarting mailscanner in the system.


NB I'd say 3 a little low for a 'low spam threshold' anyway, you're quite
likely to hit alot of ham. I'd look at what rulesets you've got and see if
iXhasf and the sought ruleset (and others) help
