This is excellent, as I will then finally be able to forward my Gentoo
alias to the work e-mail server. Like GMail, it is strict because all of
our employees hate spam.

Just speaking as a fellow mail server operator, our automatic throwing
away happens at a score of 8 or above. Between 5 and 8, it is dropped in
a quarantine for sorting by a human.
The amount of false positives is incredibly low, but some of our users
are incredibly vocal. Some of them rely on the human to release that one
mail a month, others are set as spam_lover in amavis and get those
e-mails scoring between 5 & 8 delivered to them.

From a man-power perspective the quarantine may not be realistic, but
perhaps this "spam_lovers" is a good way to allow the opt-out that Eray
is trying to negotiate?
