The parameter value is case- insensitive and can be either &#8220;yes&#8221; or &#8220;no&#8221;. Setting the value to &#8220;no&#8221; is meaningful when used within S&#8203;/&#8203;MIME or PGP/MIME signed or encrypted body parts (cf. <a href="#I-D.ietf-lamps-header-protection-requirements" class="xref">[I-D.ietf-lamps-header-protection-requirements]</a>.

    3.85 -1.  Introduction
    3.86 -
    3.87 -   This document defines a new Content-Type header field parameter
    3.88 -   [RFC2045] for "message/rfc822" and "message/global" [RFC6532] media
    3.89 -   types with name "forwarded".  The parameter value is case-
    3.90 -   insensitive and can be either "yes" or "no".  Setting the value to
    3.91 -   "no" is meaningful when used within S/MIME or PGP/MIME signed or
    3.92 -   encrypted body parts (cf.
    3.93 -   [I-D.ietf-lamps-header-protection-requirements].  The value "yes"
    3.94 -   means that the message nested inside "message/rfc822" (or "message/
    3.95 -   global") is a simple forwarded message.  If the parameter is missing,
    3.96 -   the default assumption is the message has been forwarded.
    3.97 -
    3.98 -1.1.  Use Cases
    3.99 -
   3.100 -   Two use cases have been discovered so far:
   3.101 -
   3.102 -   1.  This parameter indicates whether a nested message is signed and/
   3.103 -       or encrypted (S/MIME or PGP/MIME), which tells the receiving side
   3.104 -       how to display the message to the user.  Currently, many email
   3.105 -       clients display "weird artefacts" to users due to this missing
   3.106 -       information.
   3.107 -
   3.108 -   2.  This parameter indicates to mailing lists which email messages
   3.109 -       are forwarded, and which are signed and/or encrypted (S/MIME or
   3.110 -       PGP/MIME), and how to handle these respective messages.

   3.118 -
   3.119 -
   3.120 -1.2.  Implementations
   3.121 -
   3.122 -   At this time, there are two known email systems which use this
   3.123 -   Content-Type header field parameter:
   3.124 -
   3.125 -   1.  Isode with S/MIME [RFC8551]
   3.126 -
   3.127 -   2.  pEp with PGP/MIME [I-D.birk-pep]
   3.128 -
   3.129 -1.3.  Requirements Language
   3.130 -
   3.131 -   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   3.132 -   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   3.133 -   document are to be interpreted as described in [RFC2119].
   3.134 -
   3.135 -1.4.  Terms
   3.136 -
   3.137 -   The following terms are defined for the scope of this document:
   3.138 -
   3.139 -   o  Header Field (HF): cf. [RFC5322]
   3.140 -
   3.141 -   o  Header Section (HS): cf. [RFC5322]
   3.142 -
   3.143 -2.  Specification
   3.144 -
   3.145 -   This section defines the new "forwarded" Content-Type header field
   3.146 -   parameter.
   3.147 -
   3.148 -   The Content-Type header field parameter "forwarded" may assume three
   3.149 -   values:
   3.150 -
   3.151 -   o  "yes": The email message contained in the MIME part is a forwarded
   3.152 -      message.  A MUA (Mail User Agent) that is forwarding a message
   3.153 -      should add a Content-Type header field parameter "forwarded=yes".
   3.154 -
   3.155 -   o  "no": The email message contained in the MIME part is a
   3.156 -      encapsulated email message that has been signed and/or encrypted
   3.157 -      for header protection.  MUAs SHOULD add a Content-Type header
   3.158 -      field parameter "forwarded=no" to indicate the message is not
   3.159 -      forwarded, but encapsulated for header protection (cf.
   3.160 -      [I-D.ietf-lamps-header-protection-requirements]).
   3.161 -
   3.162 -   o  absent: If the MUA has no information to determine whether an
   3.163 -      email message is forwarded or encapsulated, it omits the
   3.164 -      "forwarded" Content-Type header field parameter.  A receiving MUAs
   3.165 -      default behavior is to assume the email message contained in the
   3.166 -      MIME part is a forwarded message.

   3.180 -   forwarded, but encapsulated in another email message.

   3.232 -4.  Security Considerations
   3.233 -
   3.234 -   This document does not define a new protocol, and thus does not
   3.235 -   create new security concerns in and of itself.
   3.236 -
   3.237 -5.  Privacy Considerations
   3.238 -
   3.239 -   This document does not introduce any new issues regarding Privacy.
   3.240 -
   3.241 -6.  IANA Considerations
   3.242 -
   3.243 -   This document requests IANA to register the Content-Type header field
   3.244 -   parameter [RFC2045] with name "forwarded" for "message/rfc822" and
   3.245 -   "message/global" media types as specified in Section 2 of this
   3.246 -   document.

   3.248 -7.  Acknowledgments
   3.249 -
   3.250 -   The authors would like to thank the following people who have
   3.251 -   provided helpful comments and suggestions for this document: David
   3.252 -   Wilson, Kelly Bristol, Krista Bennett, Robert Williams, Steve Kille,
   3.253 -   and Wei Chuang.
   3.254 -
   3.255 -   David Wilson came up with the idea of defining a new Content-Type
   3.256 -   header field parameter to distinguish forwarded messages from inner
   3.257 -   header field protection constructs.

   4.369 -<abstract><t>The pretty Easy privacy (pEp) model and protocols describe a set of conventions for the automation of operations traditionally seen as barriers to the use and deployment of secure, privacy-preserving end- to-end interpersonal messaging.  These include, but are not limited to, key management, key discovery, and private key handling (including peer-to-peer synchronization of private keys and other user data across devices).  Human Rights-enabling principles like Data Minimization, End-to-End and Interoperability are explicit design goals.  For the goal of usable privacy, pEp introduces means to verify communication between peers and proposes a trust-rating system to denote secure types of communications and signal the privacy level available on a per-user and per-message level. Significantly, the pEp protocols build on already available security formats and message transports (e.g., PGP/MIME with email), and are written with the intent to be interoperable with already widely- deployed systems in order to ease adoption and implementation.  This document outlines the general design choices and principles of pEp.</t></abstract>
