mail: Bounce-Abruf liest RFC 6533, All-Inkl-Freitext und ganze INBOX

Browse source 
Befund aus 151 echten Rücklaeufern: 2 SmarterMail-DSNs
(message/global-delivery-status) und 2 Freitext-Hinweise des eigenen
Relays (X-KASMail-Error, formal auto-replied) fielen durch. Policy- und
Quota-Codes zaehlen weich statt hart. Abruf ohne UNSEEN-Filter, weil
das Verschieben die Zustandsmarke ist.

Dazu Schutz in tests/TestCase.php: Suite bricht ab, wenn ein Config-Cache
sie auf die Dev-Datenbank umlenkt.
