I suggest to simply use a good spam filter and enqueue marked e-mails
in a separate queue which is maintained by a human, so "learning data"
can be collected and the false-positive rate can be reduced. I think
discarding e-mails is not useful.

But when using spam filters keep in mind that people who send spam
also use them for testing purposes and optimise their e-mails to pass
the filter.
But generally speaking I think the spam rate on the FSF Europe mailing
lists is quite low and if someone cleans the archive, I don't care about
less than 1% spam.
