The Sieve Email Filtering Language (RFC 5228) is a popular email filtering language
used upon final mail delivery.
This document creates a registry of for Sieve (RFC 5228) actions in order to help developers and

<t>
The Sieve Email Filtering Language <xref target="RFC5228"/> target="RFC5228" format="default"/> is a popular email filtering language
used upon final mail delivery. Popularity The popularity of Sieve resulted in a myriad of Sieve extensions
that can interact with each other in wonderful and complex ways.
There
Currently, there is currently no easy way to find out all actions defined by Sieve extensions published
in RFCs, which make makes it quite difficult for Sieve extension writers and Sieve implementation
developers to forsee foresee interactions between Sieve actions.

IANA is requested to create a new has created the "Sieve Actions" registry for Sieve actions (see Section 2.9 of <xref target="RFC5228"/> target="RFC5228" section="2.9" sectionFormat="of"/>
for details on Sieve actions). Registration of both actions specified in IETF Stream both RFCs
and vendor specific actions vendor-specific documentation is allowed and encouraged.

Registration
The registration procedure for this registry is Expert Review. Review <xref target="RFC8126"/>.
The Designated Expert 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 referenced, and that the list of
relevant documents is as complete as possible.
The Designated Expert can’t designated expert can't reject a registration based on because of a personal dislike of for
the document defining an action and should always err on the side of registering, approving the registration,
even if documentation is not complete.

The sole purpose of this document is to create a new IANA registry,
so the "Sieve Actions" registry;
therefore, it doesn't create new security considerations for Sieve implementations.
</t>
<t>
The new registry should help Sieve extension writers and Sieve implementors
track interactions between different Sieve actions, so actions; therefore, it might improve the quality
of specifications and implementations, including security aspects.
</t>
<t>
For the Security Considerations of security considerations related to particular actions, see the RFC(s) one or more RFCs referenced
for that the action in the Initial Sieve Action Registry question in <xref target="initial-regs"/>. the "Sieve Actions" registry (<xref target="initial-regs" format="default"/>).
