Table of Contents

1. Introduction

JMAP <> 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 <>. Email object and methods are defined in <>.

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.

2. Email/createMDN

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

It takes the following arguments:

An MDN object has the following properties:

A Disposition object has the following properties:

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:

3. IANA Considerations
