Sieve Editor CRAM-MD5 Fork

This repository contains the ecxod/sieve fork of Sieve Editor. It provides a standalone Windows application and a Thunderbird extension for managing server-side Sieve mail-filter scripts over ManageSieve.

The fork adds CRAM-MD5 authentication and maintains a small set of documented usability changes. See README_FORK.md for the exact differences from the upstream project.

Stable release 0.8.6

Version 0.8.6 is the latest stable release for both the Windows EXE and the Thunderbird XPI.

Release 0.8.6 uses the same version for the Windows application and the Thunderbird extension. The extension includes:

• CRAM-MD5 authentication and a Thunderbird-compatible ManageSieve socket implementation using the current asynchronous STARTTLS API
• automatic discovery of Thunderbird IMAP and POP accounts whenever the Sieve server list is rendered
• an optional Create Server flow for standalone ManageSieve servers that do not correspond to a Thunderbird mail account
• safe removal of manually created server configurations without deleting mail accounts or server-side Sieve scripts
• a standard Thunderbird Options page with I am a developer; the per-server Debugging control stays hidden unless developer mode is enabled
• optional Sentry error reporting configured by the user on the Options page; reporting is disabled while the DSN field is empty, and the extension contains no hard-coded project DSN
• a Thunderbird → Sieve tab for each discovered mail server, showing Thunderbird message filters beside conservatively generated Sieve blocks
• comparison with the server's existing Sieve scripts; matching imported blocks are highlighted in yellow
• per-rule Edit, Copy stanza, and guarded Thunderbird-filter deletion controls, plus a sticky refresh/copy-all toolbar
• direct insertion into a selected existing server script, including missing require capabilities, full-script syntax validation, and protection against overwriting a script changed since the table was loaded; script activation is never changed by the importer
• a Make pretty action in the source editor that indents nested blocks, string lists, and test arguments while preserving strings, comments, and multiline text; editor settings control tabs/spaces, compact or multiline lists and tests, whether opening block braces start on a new line, and optional blank lines after the leading require section and complete if/elsif/else chains
• a Spam tab for browsing, searching, and selecting messages in the account's spam folder; selected messages can be restored safely to INBOX, and matching allow/block rules can be inspected or appended to a chosen Sieve script without overwriting an independently changed script
• a save-or-discard warning when an editor with changes relative to the loaded server script is closed; cancelling or a failed save keeps the editor open
• a visible add-on name beside Create Server and the fork/version footer used by the Windows application

Unsupported, disabled, or semantically different Thunderbird rules are emitted with a false guard and warnings for manual review rather than being silently enabled on the server.

The Windows application additionally provides a portable settings backup. It exports and restores server accounts, logins, editor and appearance settings, and optional error-tracking settings. Remembered passwords are included only after an explicit choice and a clear-text warning. The global Settings tab also contains update management which displays the installed and latest GitHub release versions and can download, verify, and start the matching Windows installer.

The Thunderbird package supports Thunderbird 121 through 154. Because it uses MailExtension Experiments, each new Thunderbird major version must be verified before the maximum compatibility version is raised.

Versions through 0.6.1.8 used the upstream extension ID. When migrating from one of those versions, remove the old Sieve extension before installing this fork. Updates from 0.6.1.9 and newer retain the fork's extension ID.

Downloads

The Windows installer and release artifacts are published on the ecxod/sieve Releases page. Checksums and package names are documented in README_FORK.md.

Build and test

Install the pinned dependencies and run the test suite:

npm ci
npm test
npm run lint

Create the Thunderbird package:

npm exec -- gulp wx:package-xpi

Create the Windows application directory:

npm exec -- gulp app:package-win32

The gulp/ directory is required. It contains the active tasks that assemble shared sources, package the Electron application and Thunderbird extension, and prepare the test suite. More details are available in BUILD.md.
