1. Introduction
Sieve Email Filtering Language [RFC5228] is a popular email filtering
language used upon final mail delivery. Popularity of Sieve resulted
in a myriad of Sieve extensions that can interact with each other in
wonderful and complex ways. There is currently no easy way to find
out all actions defined by Sieve extensions published in RFCs, which
make it quite difficult for Sieve extension writers and Sieve
implementation developers to forsee interactions between Sieve
actions.
This document creates a registry of Sieve [RFC5228] actions in order
to help developers and Sieve extension writers track interactions
between different extensions.
2. Conventions Used in This Document
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.
3. IANA Considerations
3.1. Sieve Actions Registration Template and Procedure
IANA is requested to create a new registry for Sieve actions (see
Section 2.9 of [RFC5228] for details on Sieve actions). Registration
of both actions specified in IETF Stream RFCs and vendor specific
actions is allowed and encouraged. The registration template
contains:
1. name of the action;
Melnikov & Murchison Expires 8 September 2022 [Page 2]
Internet-Draft IANA registry for Sieve actions March 2022
2. short description;
3. references: one or more documents describing the action and any
significant updates to its definition (this field is REQUIRED for
actions described in RFCs and OPTIONAL otherwise);
4. name(s) of Sieve capabilit(ies) associated with the Sieve action
being registered;
5. interactions with other Sieve actions, if any;
6. flag specifying whether the action cancels the implicit keep (see
Section 2.10.2 of [RFC5228]);
7. whether or not this action can be used with IMAP events in Sieve
([RFC6785]), and
8. optional comment.
Registration procedure for this registry is Expert Review. The
Designated Expert only checks that the name of the action being
registered matches documentation, that the description field is
accurate, that the correct documents are referenced and that the list
of relevant documents is as complete as possible. The Designated
Expert can't reject a registration based on personal dislike of the
document defining an action and should always err on the side of
registering, even if documentation is not complete.
Addition of a new reference to an existing registration or change to
the description field goes through the same registration procedure as
a new registration.
3.2. Initial Sieve Action Registry
The following table is used to initialize the actions registry.

4. Security Considerations
The sole purpose of this document is to create a new IANA registry,
so it doesn't create new security considerations for Sieve
implementations.
The new registry should help Sieve extension writers and Sieve
implementors track interactions between different Sieve actions, so
it might improve quality of specifications and implementations,
including security aspects.
