The filter in front of the mailbox scores every delivered message and
writes its working into headers, and none of it was being read. A message
in Junk gave no reason for being there.
Nothing here scores anything. The headers are parsed and shown, so this
cannot disagree with the filter that actually made the decision.
Two formats cover what sits in front of a Stalwart mailbox in practice:
the SpamAssassin-shaped X-Spam-* set, which Stalwart's own filter writes,
and Rspamd's X-Spamd-Result. A header in neither shape is left unread
rather than guessed at, since a misparsed score shown confidently is worse
than no panel at all. Mail that arrived without any of them shows nothing.
Rules are listed largest mover first and signed, because which way a rule
pushed is the point, and the biggest contributor is the answer to why the
message scored what it did.
Two things it deliberately will not do. A score is always given the
threshold it was measured against, because 6.7 is damning against 5 and
unremarkable against 15 -- the number alone is not something a reader can
act on; where no threshold was stated, it says so rather than implying
one. And where the filter recorded no verdict, none is derived from score
against threshold: the filter applies policy we cannot see, and putting a
verdict in its mouth would be inventing one.
The mock writes the same headers at delivery -- spam in Junk, clean in the
Inbox, nothing on mail this account wrote -- so the panel can be developed
and demoed against it.
