RFC5173 - Sieve Email Filtering: Body Extension
This document defines a new command for the "Sieve" email filtering language that tests for the occurrence of one or more strings in the body of an email message. [STANDARDS-TRACK]
RFC5228 - Sieve: An Email Filtering Language
This document describes a language for filtering email messages at time of final delivery. It is designed to be implementable on either a mail client or mail server. It is meant to be extensible, simple, and independent of access protocol, mail architecture, and operating system. It is suitable for running on a mail server where users may not be allowed to execute arbitrary programs, such as on black box Internet Message Access Protocol (IMAP) servers, as the base language has no variables, loops, or ability to shell out to external programs. [STANDARDS-TRACK]
RFC5229 - Sieve Email Filtering: Variables Extension
In advanced mail filtering rule sets, it is useful to keep state or configuration details across rules. This document updates the Sieve filtering language (RFC 5228) with an extension to support variables. The extension changes the interpretation of strings, adds an action to store data in variables, and supplies a new test so that the value of a string can be examined. [STANDARDS-TRACK]
RFC5230 - Sieve Email Filtering: Vacation Extension
This document describes an extension to the Sieve email filtering language for an autoresponder similar to that of the Unix "vacation" command for replying to messages. Various safety features are included to prevent problems such as message loops. [STANDARDS-TRACK]
RFC5231 - Sieve Email Filtering: Relational Extension
This document describes the RELATIONAL extension to the Sieve mail filtering language defined in RFC 3028. This extension extends existing conditional tests in Sieve to allow relational operators. In addition to testing their content, it also allows for testing of the number of entities in header and envelope fields.
This document obsoletes RFC 3431. [STANDARDS-TRACK]
RFC5232 - Sieve Email Filtering: Imap4flags Extension
Recent discussions have shown that it is desirable to set different IMAP (RFC 3501) flags on message delivery. This can be done, for example, by a Sieve interpreter that works as a part of a Mail Delivery Agent.
This document describes an extension to the Sieve mail filtering language for setting IMAP flags. The extension allows setting of both IMAP system flags and IMAP keywords. [STANDARDS-TRACK]
RFC5233 - Sieve Email Filtering: Subaddress Extension
On email systems that allow for 'subaddressing' or 'detailed addressing' (e.g., "ken+sieve@example.org"), it is sometimes desirable to make comparisons against these sub-parts of addresses. This document defines an extension to the Sieve Email Filtering Language that allows users to compare against the user and detail sub-parts of an address. [STANDARDS-TRACK]
RFC5235 - Sieve Email Filtering: Spamtest and Virustest Extensions
The Sieve email filtering language "spamtest", "spamtestplus", and "virustest" extensions permit users to use simple, portable commands for spam and virus tests on email messages. Each extension provides a new test using matches against numeric "scores". It is the responsibility of the underlying Sieve implementation to do the actual checks that result in proper input to the tests. [STANDARDS-TRACK]
RFC5293 - Sieve Email Filtering: Editheader Extension
This document defines two new actions for the "Sieve" email filtering language that add and delete email header fields. [STANDARDS-TRACK]
RFC5429 - Sieve Email Filtering: Reject and Extended Reject Extensions
This memo updates the definition of the Sieve mail filtering language "reject" extension, originally defined in RFC 3028.
A "Joe-job" is a spam run forged to appear as though it came from an innocent party, who is then generally flooded by automated bounces, Message Disposition Notifications (MDNs), and personal messages with complaints. The original Sieve "reject" action defined in RFC 3028 required use of MDNs for rejecting messages, thus contributing to the flood of Joe-job spam to victims of Joe-jobs.
This memo updates the definition of the "reject" action to allow messages to be refused during the SMTP transaction, and defines the "ereject" action to require messages to be refused during the SMTP transaction, if possible.
The "ereject" action is intended to replace the "reject" action wherever possible. The "ereject" action is similar to "reject", but will always favor protocol-level message rejection. [STANDARDS-TRACK]
RFC5435 - Sieve Email Filtering: Extension for Notifications
Users go to great lengths to be notified as quickly as possible that they have received new mail. Most of these methods involve polling to check for new messages periodically. A push method handled by the final delivery agent gives users quicker notifications and saves server resources. This document does not specify the notification method, but it is expected that using existing instant messaging infrastructure such as Extensible Messaging and Presence Protocol (XMPP), or Global System for Mobile Communications (GSM) Short Message Service (SMS) messages will be popular. This document describes an extension to the Sieve mail filtering language that allows users to give specific rules for how and when notifications should be sent. [STANDARDS-TRACK]
RFC5436 - Sieve Notification Mechanism: mailto
This document describes a profile of the Sieve extension for notifications, to allow notifications to be sent by electronic mail. [STANDARDS-TRACK]
RFC5437 - Sieve Notification Mechanism: Extensible Messaging and Presence Protocol (XMPP)
This document describes a profile of the Sieve extension for notifications, to allow notifications to be sent over the Extensible Messaging and Presence Protocol (XMPP), also known as Jabber. [STANDARDS-TRACK]
RFC5463 - Sieve Email Filtering: Ihave Extension
This document describes the "ihave" extension to the Sieve email filtering language. The "ihave" extension provides a means to write scripts that can take advantage of optional Sieve features but can still run when those optional features are not available. The extension also defines a new error control command intended to be used to report situations where no combination of available extensions satisfies the needs of the script. [STANDARDS-TRACK]
RFC5490 - The Sieve Mail-Filtering Language -- Extensions for Checking Mailbox Status and Accessing Mailbox Metadata
This memo defines an extension to the Sieve mail filtering language (RFC 5228) for accessing mailbox and server annotations, checking for mailbox existence, and controlling mailbox creation on "fileinto" action. [STANDARDS-TRACK]
RFC5703 - Sieve Email Filtering: MIME Part Tests, Iteration, Extraction, Replacement, and Enclosure
This document defines extensions to the Sieve email filtering language to permit analysis and manipulation of the MIME body parts of an email message. [STANDARDS-TRACK]
RFC5784 - Sieve Email Filtering: Sieves and Display Directives in XML
This document describes a way to represent Sieve email filtering language scripts in XML. Representing Sieves in XML is intended not as an alternate storage format for Sieve but rather as a means to facilitate manipulation of scripts using XML tools.
The XML representation also defines additional elements that have no counterparts in the regular Sieve language. These elements are intended for use by graphical user interfaces and provide facilities for labeling or grouping sections of a script so they can be displayed more conveniently. These elements are represented as specially structured comments in regular Sieve format. [STANDARDS-TRACK]
RFC5804 - A Protocol for Remotely Managing Sieve Scripts
Sieve scripts allow users to filter incoming email. Message stores are commonly sealed servers so users cannot log into them, yet users must be able to update their scripts on them. This document describes a protocol "ManageSieve" for securely managing Sieve scripts on a remote server. This protocol allows a user to have multiple scripts, and also alerts a user to syntactically flawed scripts. [STANDARDS TRACK]
RFC6009 - Sieve Email Filtering: Delivery Status Notifications and Deliver-By Extensions
This document describes the "envelope-dsn", "redirect-dsn", "envelope-deliverby", and "redirect-deliverby" extensions to the Sieve email filtering language. The "envelope-dsn" and "envelope- deliverby" extensions provide access to additional envelope information provided by the delivery status notification (DSN) and Deliver-By SMTP extensions, respectively. The "redirect-dsn" and "redirect-deliverby" extensions extend Sieve's redirect action to provide control over delivery status notification and Deliver-By parameters, respectively. [STANDARDS-TRACK]
RFC6131 - Sieve Vacation Extension: "Seconds" Parameter
This document describes a further extension to the Sieve Vacation extension, allowing multiple auto-replies to the same sender in a single day by adding a ":seconds" parameter. [STANDARDS-TRACK]
RFC6132 - Sieve Notification Using Presence Information
This is a further extension to the Sieve mail filtering language Notification extension, defining presence information that may be checked through the notify_method_capability feature. [STANDARDS-TRACK]
RFC6133 - Sieve Email Filtering: Use of Presence Information with Auto-Responder Functionality
This document describes how the Sieve email filtering language, along with some extensions, can be used to create automatic replies to incoming electronic mail messages based on the address book and presence information of the recipient. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6134 - Sieve Extension: Externally Stored Lists
The Sieve email filtering language can be used to implement email whitelisting, blacklisting, personal distribution lists, and other sorts of list matching. Currently, this requires that all members of such lists be hard-coded in the script itself. Whenever a member of a list is added or deleted, the script needs to be updated and possibly uploaded to a mail server.
This document defines a Sieve extension for accessing externally stored lists -- lists whose members are stored externally to the script, such as using the Lightweight Directory Access Protocol (LDAP), the Application Configuration Access Protocol (ACAP), vCard Extensions to WebDAV (CardDAV), or relational databases. [STANDARDS-TRACK]
RFC6468 - Sieve Notification Mechanism: SIP MESSAGE
This document describes a profile of the Sieve extension for notifications, to allow notifications to be sent over SIP MESSAGE. [STANDARDS-TRACK]
RFC6558 - Sieve Extension for Converting Messages before Delivery
This document describes how the "CONVERT" IMAP extension can be used within the Sieve mail filtering language to transform messages before final delivery. [STANDARDS-TRACK]
RFC6609 - Sieve Email Filtering: Include Extension
The Sieve Email Filtering "include" extension permits users to include one Sieve script inside another. This can make managing large scripts or multiple sets of scripts much easier, and allows a site and its users to build up libraries of scripts. Users are able to include their own personal scripts or site-wide scripts. [STANDARDS-TRACK]
RFC6785 - Support for Internet Message Access Protocol (IMAP) Events in Sieve
Sieve defines an email filtering language that can, in principle, plug into any point in the processing of an email message. As defined in the base specification, it plugs into mail delivery. This document defines how Sieve can plug into points in IMAP where messages are created or changed, adding the option of user-defined or installation-defined filtering (or, with Sieve extensions, features such as notifications). Because this requires future Sieve extensions to specify their interactions with this one, this document updates the base Sieve specification, RFC 5228. [STANDARDS-TRACK]
