.  Introduction

   JMAP <https://tools.ietf.org/html/draft-ietf-jmap-core-06> is a
   generic protocol for synchronising data, such as mail, calendars or
   contacts, between a client and a server.  It is optimised for mobile
   and web environments, and aims to provide a consistent interface to
   different data types.

   This specification defines a method helping to send MDN (Message
   Disposition Nodification) messages.  MDN are defined in [RFC8098] and
   are used as "read receipts", "acknowledgements", or "receipt
   notifications".

1.1.  Notational conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   Type signatures, examples and property descriptions in this document
   follow the conventions established in Section 1.1 of
   <https://tools.ietf.org/html/draft-ietf-jmap-core-06>.  Email object
   and methods are defined in <https://tools.ietf.org/html/draft-ietf-
   jmap-mail-06>.

1.2.  Terminology

   The same terminology is used in this document as in the core JMAP
   specification.

1.3.  Addition to the capabilities object

   The capabilities object is returned as part of the standard JMAP
   Session object; see the JMAP spec.  Servers supporting _this_
   specification MUST add a property called "urn:ietf:params:jmap:mdn"
   to the capabilities object.

.  Email/createMDN

   The Email/createMDN method create a [RFC5322] message from MDN
   properties.

   It takes the following arguments:

   o  *accountId*: "String|null" The id of the account to use for this
      call.  If "null", defaults to the "urn:ietf:params:jmap:mail"
      primary account.

   o  *mdns*: "String[MDN]" A map of creation id (client specified) to
      MDN objects

   An *MDN* object has the following properties:

   o  *referencedMessageId*: "String" Message Id of the received message
      the user wants to create an MDN for.

   o  *subject*: "String" Subject that will be used as "Subject" header
      for this MDN.

   o  *textBody*: "String" Human readable part of the MDN, as plain
      text.

   o  *reportingUA*: "String" Name of the MUA creating this MDN.  It is
      used to build the MDN Report part of the MDN.

   o  *disposition*: "Disposition" Object containing the diverse MDN
      disposition options.

   A *Disposition* object has the following properties:

   o  *actionMode*: "String" This MUST be one of the following strings:
      "manual-action" / "automatic-action"

   o  *sendingMode*: "String" This MUST be one of the following strings:
      "MDN-sent-manually" / "MDN-sent-automatically"

   o  *type*: "String" This MUST be one of the following strings:
      "deleted" / "dispatched" / "displayed" / "processed"

   See [RFC8098] for the exact meaning of these different fields.

   If the _referencedMessageId_, _subject_, _textBody_, _reportingUA_,
   _disposition_ properties are invalid (e.g. missing, wrong type, id
   not found), the server MUST reject the import with an
   "invalidProperties" SetError.

   If the email cannot be created because it would take the account over
   quota, the creation should be rejected with a "maxQuotaReached"
   SetError.

   The response has the following arguments:

   o  *accountId*: "String" The id of the account used for this call.

   o  *created*: "String[Email]" A map of the creation id to an object
      build from the referenced properties.  The _blobId_ field of the
      Email objects can then be used to effectively send the MDN.

   o  *notCreated*: "String[SetError]" A map of creation id to a
      SetError object for each Email that failed to be created.  The
      possible errors are defined above.

.  IANA Considerations

3.1.  JMAP Capability Registration for "mdn"

   IANA will register the "mdn" JMAP Capability as follows:

   Capability Name: "urn:ietf:params:jmap:mdn"

   Specification document: this document

   Intended use: common

   Change Controller: IETF

   Security and privacy considerations: this document, section 4.
