1. Introduction
JMAP [RFC8620] (JSON Meta Application Protocol) is a generic protocol for synchronizing data, such as mail, calendars or contacts, between a client and a server. It is optimized for mobile and web environments, and aims to provide a consistent interface to different data types.¶
This specification defines a data model for managing Sieve [RFC5228] scripts on a server using JMAP. The data model is designed to allow a server to provide consistent access to the same scripts via ManageSieve [RFC5804] as well as JMAP.¶
1.1. Notational Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
Type signatures, examples, and property descriptions in this document follow the conventions established in Section 1.1 of [RFC8620]. This document also uses data types and terminology established in Sections 1.2-1.6 of [RFC8620].¶
The term SieveScript (with this specific capitalization) is used to refer to the data type defined in this document and instances of those data types. Servers MUST support all properties specified for the data type defined in this document.¶
For brevity, JMAP API (see Section 3 of [RFC8620]) examples only show the "methodCalls" property of the Request object, and the "methodResponses" property of the Response object. All other examples are shown using the HTTP 1.1 [RFC9112] protocol.¶
1.2. Addition to the Capabilities Object
The capabilities object is returned as part of the JMAP Session object; see [RFC8620], Section 2. This document defines one additional capability URI.¶
1.2.1. urn:ietf:params:jmap:sieve
The urn:ietf:params:jmap:sieve URI represents support for the SieveScript data type and associated API methods. The value of this property in the JMAP Session capabilities property is an object that MUST contain the following information on server capabilities:¶
The value of this property in an account's accountCapabilities property is an object that MUST contain the following information on per-account server capabilities:¶
-
maxSizeScriptName:
UnsignedInt
¶The maximum length, in octets, allowed for the name of a SieveScript. For compatibility with ManageSieve, this MUST be at least 512 (up to 128 Unicode characters).¶
-
maxSizeScript:
UnsignedInt|null
¶The maximum size (in octets) of a Sieve script the server is willing to store for the user, or
null
for no limit.¶ -
maxNumberScripts:
UnsignedInt|null
¶The maximum number of Sieve scripts the server is willing to store for the user, or
null
for no limit.¶ -
maxNumberRedirects:
UnsignedInt|null
¶The maximum number of Sieve "redirect" actions a script can perform during a single evaluation or
null
for no limit. Note that this is different from the total number of "redirect" actions a script can contain.¶ -
sieveExtensions:
String[]
¶A list of case-sensitive Sieve capability strings (as listed in Sieve "require" action; see [RFC5228], Section 3.2) indicating the extensions supported by the Sieve engine.¶
-
notificationMethods:
String[]|null
¶A list of URI schema parts [RFC3986] for notification methods supported by the Sieve "enotify" [RFC5435] extension, or
null
if the extension is not supported by the Sieve engine.¶ -
externalLists:
String[]|null
¶A list of URI schema parts [RFC3986] for externally stored list types supported by the Sieve "extlists" [RFC6134] extension, or
null
if the extension is not supported by the Sieve engine.¶
1.2.2. Example
A JMAP Session object showing a user that has access to their own Sieve scripts with support for a few Sieve extensions:¶
{ "capabilities": { "urn:ietf:params:jmap:core": { ... }, "urn:ietf:params:jmap:mail": {}, "urn:ietf:params:jmap:quota": {}, "urn:ietf:params:jmap:blob": {}, "urn:ietf:params:jmap:sieve": { "implementation": "ACME Email Filtering" }, "urn:ietf:params:jmap:vacationresponse": {}, ... }, "accounts": { "ken": { "name": "ken@example.com", "isPersonal": true, "isReadOnly": false, "accountCapabilities": { "urn:ietf:params:jmap:core": {}, "urn:ietf:params:jmap:quota": {}, "urn:ietf:params:jmap:mail": { ... }, "urn:ietf:params:jmap:blob": { "supportedTypeNames": [ "Email" "SieveScript", ... ], ... }, "urn:ietf:params:jmap:sieve": { "maxSizeScriptName": 512, "maxSizeScript": 65536, "maxNumberScripts": 5, "maxNumberRedirects": null, "sieveExtensions": [ "fileinto", "imap4flags", "enotify", ... ], "notificationMethods": [ "mailto" ], "externalLists": null, }, "urn:ietf:params:jmap:vacationresponse": {}, ... }, ... } }, "primaryAccounts": { "urn:ietf:params:jmap:mail": "ken", "urn:ietf:params:jmap:sieve": "ken", "urn:ietf:params:jmap:vacationresponse": "ken", ... }, "username": "ken@example.com", "apiUrl": "/jmap/", "downloadUrl": "/jmap/download/{accountId}/{blobId}/{name}?accept={type}", "uploadUrl": "/jmap/upload/{accountId}/", ... }¶
2. Sieve Scripts
A SieveScript object represents a single Sieve [RFC5228] script for filtering email messages at time of final delivery.¶
2.1. Sieve Script Properties
A SieveScript object has the following properties:¶
-
id:
Id
(immutable; server-set)¶The id of the script.¶
-
name:
String|null
(optional; default is server-dependent)¶User-visible name for the SieveScript. If non-null, this MUST be a Net-Unicode [RFC5198] string of at least 1 character in length, subject to the maximum size given in the capability object.¶
For compatibility with ManageSieve, servers MUST reject names that contain any of the following Unicode characters: U+0000 - U+001F, U+007F - U+009F, U+2028, U+2029.¶
Servers MAY reject names that violate server policy (e.g., names containing slash (/)).¶
The name MUST be unique among all SieveScripts within an account.¶
-
blobId:
Id
¶The id of the blob containing the raw octets of the script.¶
-
isActive:
Boolean
(server-set; default: false)¶Indicator that the SieveScript is actively filtering incoming messages.¶
A user may have at most one active script. The SieveScript/set (Section 2.4) method is used for changing the active script or disabling Sieve processing.¶
2.2. Sieve Script Content
A script MUST be UTF-8 [RFC3629] content of at least 1 character in length, subject to the syntax of Sieve [RFC5228]. A script MUST NOT contain any "require" statement(s) mentioning Sieve capability strings not present in the capability (Section 1.2.1) object. Note that if the Sieve "ihave" [RFC5463] capability string is present in the capability object, the script MAY mention unrecognized/unsupported extensions in the "ihave" test.¶
Script content is treated as a binary blob and uploaded/downloaded via the mechanisms in [RFC8620] Sections 6.1/6.2 respectively and/or via the JMAP Blob management methods in [RFC9404] Sections 4.1/4.2 respectively.¶
Downloading script content via the JMAP downloadUrl or the Blob/get method provides equivalent functionality to the GETSCRIPT command in [RFC5804].¶
2.3. SieveScript/get
This is a standard "/get" method as described in
[RFC8620], Section 5.1.
The ids argument may be
null
to fetch all scripts at once.¶
This method provides equivalent functionality to the LISTSCRIPTS command in [RFC5804].¶
2.3.1. Examples
List all scripts:¶
[ ["SieveScript/get", { "accountId": "ken" }, "0"] ] [ [ "SieveScript/get", { "state": "1634915373.240633104-120", "list": [ { "id": "2d647053-dded-418d-917a-63eda3ac8f7b", "name": "test1", "isActive": true, "blobId": "S7" } ], "notFound": [], "accountId": "ken" }, "0" ] ]¶
Download the script content via the JMAP downloadUrl as advertised in Section 1.2.2:¶
GET /jmap/download/ken/S7/test1.siv?accept=application/sieve HTTP/1.1 Host: jmap.example.com Authorization: Basic a2VuOnBhc3N3b3Jk HTTP/1.1 200 OK Date: Fri, 22 Oct 2021 15:27:38 GMT Content-Type: application/sieve; charset=utf-8 Content-Disposition: attachment; filename="test1.siv" Content-Length: 49 require ["fileinto"]; fileinto "INBOX.target";¶
Fetch script properties and content in a single JMAP API request using the JMAP Blob management extension [RFC9404]:¶
[ ["SieveScript/get", { "accountId": "ken", "ids": [ "2d647053-dded-418d-917a-63eda3ac8f7b" ] }, "0"], ["Blob/get", { "accountId": "ken", "#ids": { "resultOf": "0", "name": "SieveScript/get", "path": "/list/*/blobId" } }, "1"] ] [ [ "SieveScript/get", { "state": "1634915373.240633104-120", "list": [ { "id": "2d647053-dded-418d-917a-63eda3ac8f7b", "name": "test1", "isActive": true, "blobId": "S7" } ], "notFound": [], "accountId": "ken" }, "0" ], [ "Blob/get", { "list": [ { "id": "S7", "data:asText": "require [\"fileinto\"];\\r\\nfileinto \"INBOX.target\";\\r\\n", "size": 49 } ], "notFound": [], "accountId": "ken" }, "1" ] ]¶
2.4. SieveScript/set
This is a standard "/set" method as described in [RFC8620], Section 5.3 but with the following additional optional request arguments:¶
-
onSuccessActivateScript:
Id
¶The id of the SieveScript to activate if and only if all of the creations, modifications, and destructions (if any) succeed. (For references to SieveScript creations, this is equivalent to a creation-reference, so the id will be the creation id prefixed with a "#".) The currently active SieveScript (if any) will be deactivated before activating the specified SieveScript.¶
If omitted, or if the id is either invalid or nonexistent, it MUST be ignored and the currently active SieveScript (if any) will remain as such.¶
The id of any activated SieveScript MUST be reported in either the "created" or "updated" argument in the response as appropriate, including a value of "true" for the "isActive" property. The id of any deactivated SieveScript MUST be reported in the "updated" argument in the response, including a value of "false" for the "isActive" property.¶
-
onSuccessDeactivateScript:
Boolean
¶If
true
, the currently active SieveScript (if any) will be deactivated if and only if all of the creations, modifications, and destructions (if any) succeed. Iffalse
or omitted, the currently active SieveScript (if any) will remain as such.¶The id of any deactivated SieveScript MUST be reported in the "updated" argument in the response, including a value of "false" for the "isActive" property.¶
If both the onSuccessActivateScript and onSuccessDeactivateScript arguments are present in the request, then onSuccessDeactivateScript MUST be processed first. If neither argument is present in the request, the currently active SieveScript (if any) will remain as such.¶
This method provides equivalent functionality to the PUTSCRIPT, DELETESCRIPT, RENAMESCRIPT, and SETACTIVE commands in [RFC5804].¶
Script content must first be uploaded as per Section 2.2 prior to referencing it in a SieveScript/set call.¶
If the SieveScript can not be created or updated because it would result in two SieveScripts with the same name, the server MUST reject the request with an "alreadyExists" SetError. An "existingId" property of type "Id" MUST be included on the SetError object with the id of the existing SieveScript.¶
If the SieveScript can not be created or updated because its size exceeds the "maxSizeScript" limit, the server MUST reject the request with a "tooLarge" SetError.¶
If the SieveScript can not be created because it would exceed the "maxNumberScripts" limit or would exceed a server-imposed storage limit, the server MUST reject the request with an "overQuota" SetError.¶
The active SieveScript MUST NOT be destroyed unless it is first deactivated in a separate SieveScript/set method call.¶
The following extra SetError types are defined:¶
For "create" and "update":¶
-
invalidSieve:¶
The SieveScript content violates the Sieve [RFC5228] grammar and/or one or more extensions mentioned in the script's "require" statement(s) are not supported by the Sieve interpreter. The description property on the SetError object SHOULD contain a specific error message giving at least the line number of the first error.¶
For "destroy":¶
2.4.1. Examples
Upload a script requiring the Imap4Flags [RFC5232] Extension using the JMAP uploadUrl as advertised in Section 1.2.2:¶
POST /jmap/upload/ken/ HTTP/1.1 Host: jmap.example.com Authorization: Basic a2VuOnBhc3N3b3Jk Content-Type: application/sieve Content-Length: 98 require "imapflags"; if address :is ["To", "Cc"] "jmap@ietf.org" { setflag "\\Flagged"; } HTTP/1.1 201 Created Date: Thu, 10 Dec 2020 17:14:31 GMT Content-Type: application/json; charset=utf-8 Content-Length: 171 { "accountId": "ken", "blobId": "Gabcc83e44a6e19991c4568d0b94e1767c83dd123", "type": "application/sieve" "size": 98 }¶
Create and activate a script using the uploaded blob. Note that the response shows that an existing active script has been deactivated in lieu of the newly created script being activated.¶
[ ["SieveScript/set", { "accountId": "ken", "create": { "A": { "name": null, "blobId": "Gabcc83e44a6e19991c4568d0b94e1767c83dd123" } }, "onSuccessActivateScript": "#A" }, "0"] ] [ [ "SieveScript/set", { "oldState": "1603741717.50737918-4096", "newState": "1603741751.227268529-4096", "created": { "A": { "id": "dd1b164f-8cdc-448c-9f54", "name": "ken-20201210T171432-0", "blobId": "Sdd1b164f-8cdc-448c-9f54", "isActive": true } }, "updated": { "8abd6f4a-bcb4d-87650-3fcd": { "isActive": false } }, "destroyed": null, "notCreated": null, "notUpdated": null, "notDestroyed": null, "accountId": "ken" }, "0" ] ]¶
Update the script content using the JMAP Blob management extension [RFC9404]:¶
{ [ ["Blob/upload", { "accountId": "ken", "create": { "B": { "data": [ { "data:asText": "redirect \"ken@example.com\"\r\n;" } ], "type": "application/sieve" } } }, "1"], ["SieveScript/set", { "accountId": "ken", "update": { "dd1b164f-8cdc-448c-9f54": { "blobId": "#B" } } }, "2"] ] [ [ "Blob/upload", { "oldState": null, "newState": "1603741700.309607123-0128", "created": { "B": { "id": "G969c83e44a6e10871c4568d0b94e1767c83ddeae", "blobId": "G969c83e44a6e10871c4568d0b94e1767c83ddeae", "type": "application/sieve", "size": 29 } }, "notCreated": null, "accountId": "ken" }, "1" ], [ "SieveScript/set", { "oldState": "1603741751.227268529-4096", "newState": "1603742603.309607868-4096", "created": null, "updated": { "dd1b164f-8cdc-448c-9f54": null }, "destroyed": null, "notCreated": null, "notUpdated": null, "notDestroyed": null, "accountId": "ken" }, "2" ] ]¶
Update the script name and deactivate it:¶
[ ["SieveScript/set", { "accountId": "ken", "update": { "dd1b164f-8cdc-448c-9f54": { "name": "myscript" } }, "onSuccessDeactivateScript": true }, "3"] ] [ [ "SieveScript/set", { "oldState": "1603742603.309607868-4096", "newState": "1603742967.852315428-4096", "created": null, "updated": { "dd1b164f-8cdc-448c-9f54": { "isActive": false } }, "destroyed": null, "notCreated": null, "notUpdated": null, "notDestroyed": null, "accountId": "ken" }, "3" ] ]¶
Reactivate the script:¶
[ ["SieveScript/set", { "accountId": "ken", "onSuccessActivateScript": "dd1b164f-8cdc-448c-9f54" }, "4"] ] [ [ "SieveScript/set", { "oldState": "1603742967.852315428-4096", "newState": "1603744460.316617118-4096", "created": null, "updated": { "dd1b164f-8cdc-448c-9f54": { "isActive": true } }, "destroyed": null, "notCreated": null, "notUpdated": null, "notDestroyed": null, "accountId": "ken" }, "4" ] ]¶
Deactivate and destroy the active script:¶
[ ["SieveScript/set", { "accountId": "ken", "onSuccessDeactivateScript": true }, "5"], ["SieveScript/set", { "accountId": "ken", "destroy": [ "dd1b164f-8cdc-448c-9f54" ] }, "6"] ] [ [ "SieveScript/set", { "oldState": "1603744460.316617118-4096", "newState": "1603744637.575375572-4096", "created": null, "updated": { "dd1b164f-8cdc-448c-9f54": { "isActive": false } }, "destroyed": null, "notCreated": null, "notUpdated": null, "notDestroyed": null, "accountId": "ken" }, "5" ], [ "SieveScript/set", { "oldState": "1603744637.575375572-4096", "newState": "1603744637.854390875-4096", "created": null, "updated": null, "destroyed": [ "dd1b164f-8cdc-448c-9f54" ], "notCreated": null, "notUpdated": null, "notDestroyed": null, "accountId": "ken" }, "6" ] ]¶
2.5. SieveScript/query
This is a standard "/query" method as described in [RFC8620], Section 5.5. A FilterCondition object has the following properties, either of which may be omitted:¶
-
name:
String
¶The SieveScript "name" property contains the given string.¶
-
isActive:
Boolean
¶The "isActive" property of the SieveScript must be identical to the value given to match the condition.¶
The following SieveScript properties MUST be supported for sorting:¶
2.6. SieveScript/validate
This method is used by the client to verify Sieve script validity without storing the script on the server, providing equivalent functionality to the CHECKSCRIPT command in [RFC5804].¶
The method takes the following arguments:¶
-
accountId:
Id
¶The id of the account to use.¶
-
blobId:
Id
¶The id of the blob containing the raw octets of the script to validate, subject to the same requirements in Section 2.¶
The response has the following arguments:¶
-
accountId:
Id
¶The id of the account used for this call.¶
-
error:
SetError|null
¶An "invalidSieve" SetError object if the script content is invalid (see Section 2.4), or
null
if the script content is valid.¶
As with the SieveScript/set (Section 2.4) method, script content must first be uploaded as a blob using either the standard upload mechanism (see [RFC8620], Section 6.1) or the JMAP Blob management extension (see [RFC9404], Section 4.1).¶
3. Quotas
Servers SHOULD impose quotas on Sieve scripts to prevent malicious users from exceeding available storage. Administration of such quotas is outside of the scope of this specification, however [RFC9425] defines a data model for users to obtain quota details over JMAP.¶
The mechanism for handling SieveScript requests that would place a user over a quota setting is discussed in Section 2.4.¶
4. Compatibility with JMAP Vacation Response
Section 8 of [RFC8621] defines a VacationResponse object to represent an autoresponder to incoming email messages. Servers that implement the VacationResponse as a Sieve script that resides amongst other user scripts are subject to the following requirements:¶
- MUST allow the VacationResponse Sieve script to be fetched by the SieveScript/get (Section 2.3) method.¶
- MUST allow the VacationResponse Sieve script to be [de]activated via the "onSuccessActivateScript" argument to the SieveScript/set (Section 2.4) method.¶
- MUST NOT allow the VacationResponse Sieve script to be destroyed or have its content updated by the SieveScript/set (Section 2.4) method. Any such request MUST be rejected with a "forbidden" SetError. A "description" property MAY be present with an explanation that the script can only be modified by a VacationResponse/set method.¶
5. Security Considerations
All security considerations of JMAP [RFC8620] and Sieve [RFC5228] apply to this specification.¶
Additionally, implementations MUST treat Sieve script content as untrusted data. As such, script parsers MUST fail gracefully in the face of syntactically invalid or malicious content and MUST be prepared to deal with resource exhaustion (E.g., allocation of enormous strings, lists, or command blocks).¶
6. IANA Considerations
6.1. JMAP Capability Registration for "sieve"
IANA will register the "sieve" JMAP Capability as follows:¶
