Dovecot Mailbox Viewer v0.1.0

Download Dovecot-Mailbox-Viewer-Windows.exe below and double-click it. No installer, ZIP extraction, Python installation or separate _internal folder is needed. For Windows 10/11 (64-bit). Startup can take a few seconds while bundled files unpack automatically. Your original backup stays unchanged.

Added

• Version number in Help → About, diagnostic logs and Windows file properties.
• A single portable Windows executable with all application dependencies bundled.
• Public GitHub Release downloads, release notes and a SHA-256 checksum.
• A packaged application check covering startup, the welcome guide, icons, TLS,
  mailbox import, HTML preview and search from a folder containing only the EXE.

Included from the earlier development builds

• Read-only browsing of supported JetBackup/cPanel Dovecot mdbox backups.
• Archive and extracted-folder opening, with a friendly getting-started guide.
• Folder navigation, progressive message loading and reusable local search indexes.
• Search filters, supported Dovecot transaction-log status flags and diagnostic logs.
• HTML previews, inline images and optional remote images with timeouts and retry.
• Attachment cards and saving; export of individual emails as .eml.
• Help, contact details and information about DesignStack.

Packaging changes

• The direct EXE replaces the previous ZIP that required an _internal folder.
• Updated GitHub build actions to versions using Node.js 24.

Known limitations

• Main Dovecot index snapshots and map indexes are not yet supported; some backups
  have unknown status flags or ambiguous folder placement.
• Complex HTML email styling may differ from a browser.
• One-file startup unpacks support files into a temporary folder automatically.

SHA256SUMS.txt contains the download checksum. GitHub's Source code downloads are for developers.
