Legend:
* OutM(S): Outer Message (OutM) at sending side (before processing by
Transport)
* OutM(R): Outer Message at receiving side (as received by Transport)
* InM: Inner Message (that protection is applied to)
* RUFM: Receiving User Facing Message
* More-HF: Additional Header Fields (HF) in the Original Message (OrigM)
* MIME-HSp: MIME Header Section part
* Trans-HF: Header Fields added in Transit (between sending and
receiving side)
* '>': taken over / copied from last column
* '=': propagates unchanged, unless something unusual (e.g. attack)
happens
* '(*)': HF may not be prosent (in which case it is neither taken over
nor does it propagate)
* '(new)' / '(OrigM)': HF or MIME-HSp is generated depending on the
decision in {{sending-side-step-1}}, while '(new)' / '(OrigM)'
designate the default
