In private conversation with Gary, he suggested I post a reminder about
my particular test corpus. It's considerably more brutal a test case, as
it's 3 and a bit years worth of email to the contact email addresses for
the company I work at. So far it's got 9,000 ham and 7,500 spam, there's
another 12,000 messages that remain to be categorised.
This means we get email from customers complaining about credit card charges,
people forwarding spam messages to complain, genuine sales enquiries or
reseller enquiries, all sorts of things that drive spamassassin mental.
It turns out that Gary's approach is sensitive to small numbers of very
spammy words (his description) and that this is why I'm getting worse
[gary - sorry for the false alarm - it's actually something with the mail
setup on my laptop that's causing email directly from me to you to bounce.
working on it now...]
