Running Plesk for a few years now for my personal mail, and it just seems that the spam filter / SpamAssassin is not learning, at all.
I keep getting the exact same spam messages straight into my inbox over and over and over again, for months now, and always move them to the spam folder by hand. Yet Plesk never learns that those are, in fact, spam. The spam score of those does not increase at all.
How do I go about debugging this behaviour? The `autolearn` header flag stays at `no` for all mails, which seems to indicate that SpamAssassin is not learning from the messages I move by hand?
