Function admission 

pub fn admission(card: &Card, ctx: &Context<'_>) -> Admission

Whether a project may take a message (Admission), as triage decides it. Its code is looked for only where a code could change the verdict (it is what reading the whole text costs): a mailing list’s message failing DMARC (no list relays your codes), or one your provider calls spam (a code protects it). Elsewhere the verdict is the same without it.
