DKIMRep: id=<user>, <originator domain>, <registered(signing domain)>sel=<dkim-selector> rep=<reputation value> info=<good|bad|neutral|rehab>
- good: the reputation system lists the identity, it has a good reputation
- bad: the reputation system lists the identity, it has a bad reputation
- neutral: the reputation system doesn't know this identity
- rehab: the reputation system lists the identity, it had a bad reputation e.g. 30 days ago; the reputation value became neutral again
