Spam rules explained in plain English

A spam report reading URI_NOVOWEL 0.5 and HTML_MESSAGE 0.001 is technically a report and practically useless to anyone who does not administer mail servers.

Triggered rules now come with a plain explanation of what each one detected and what to change. Every rule with an available explanation is shown, not only the high-scoring ones, because a stack of small penalties is what usually pushes a message over the line.

Separately, a message detected in a spam folder is now escalated as critical rather than logged quietly. That is your earliest hard evidence that placement has gone wrong, and it should interrupt you.
