New features, improvements and fixes in Mbox Viewer for macOS.https://mboxviewer.net/enhttps://mboxviewer.net/changelog/#v2-8-2-machttps://mboxviewer.net/changelog/#v2-8-2-mac• Merging Apple Mail mailboxes tagged every message with the same origin. Apple Mail's "Export Mailbox…" writes a folder named "Inbox.mbox" containing a file called literally "mbox", so the optional X-Mbox-Source header recorded "mbox" for all of them — losing the whole point of the option, which is knowing which archive an email came from. Merged messages now carry the name you recognize, and mailboxes that would share a name are told apart by their folder. • Merging no longer requires opening a mailbox first. It is now an app-level action with its own window, available from File → Merge MBOX Files… and from a button on the welcome screen. If a mailbox is already open, it starts out in the list. • The merge window is far more usable: the list scrolls instead of pushing the window off-screen, shows each mailbox's size and a total, accepts mailboxes dropped onto it, and reports real progress while it works ("Merging 2 of 5 — Inbox.mbox"). When it finishes it tells you how it went in your own language and offers Show in Finder, Open Merged Mailbox and Close. • The toolbar explains itself. Conversation threading no longer shares an icon with Search Filters — it now uses the conversation bubbles Mail.app uses for the same thing — and the six icon-only view segments (Text, Full Headers, Properties, MIME, Raw, Hex) name themselves on hover, shortcut included: "Full Headers (⌘2)". • Menu items that need an open mailbox — File → Export, the View and Message commands, Search Filters — are greyed out with none open, instead of looking available and being silently ignored when clicked.Fri, 07 Aug 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-8-1-machttps://mboxviewer.net/changelog/#v2-8-1-mac• The search field no longer vanishes from the toolbar while you type. At certain window widths, entering a query could push it out of view with no way to bring it back until you resized the window. It now keeps a fixed width; the match count is still shown in the status bar. • ⌘F now always leads somewhere: if the search field can't be focused, it opens the Search Filters panel instead of doing nothing.Fri, 17 Jul 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-8-0-machttps://mboxviewer.net/changelog/#v2-8-0-mac• Export any message to PDF. The exported PDF keeps the same layout as printing, in a self-contained multi-page file. Exporting one message is free; batch PDF export (several at once) is a Pro feature. • Export any message to a self-contained HTML file — headers, body with inline images embedded, and attachments included as downloadable links — so it opens anywhere with no external references. Single-message export is free; batch export is Pro. • New attachments pane: a gallery that lists every attachment with a per-type icon, its content type and size, image preview and one-click save — including “Save all” to a folder. • Three new ways to inspect a message, alongside Text and Headers: a Properties view (all addresses, dates and threading identifiers, selectable and copyable), a MIME structure view (the message's part tree with content types, encoding, charset and sizes) and a Hex view (an offset · hex · ASCII dump of the raw message) — ideal for technical or forensic inspection. • Repair damaged mailboxes (Pro). When a mailbox opens empty or as one giant message, its “From ” separators were probably lost; a deep-scan recovery re-detects the message boundaries. You can rebuild the view in place or export a brand-new, repaired .mbox copy — and the original file is never modified (the app stays strictly read-only). • Merge mailboxes with full traceability: a new option adds an “X-Mbox-Source” header to each merged message with its origin file name, so a combined archive still shows which mailbox every email came from. Off by default, and it works with or without duplicate removal.Mon, 13 Jul 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-7-1-machttps://mboxviewer.net/changelog/#v2-7-1-mac• The “Merge Mailboxes” picker no longer greys out your mailboxes: you can now select any recognizable mailbox — including extensionless Thunderbird mailboxes (INBOX, Sent…), .mbs/.mbx archives, files on a NAS, and Apple Mail “Name.mbox” export folders. • Merging up to 1 GB of combined mailboxes is free; larger merges are now a Pro feature, shown with a clear notice and an upgrade option.Sat, 04 Jul 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-7-0-machttps://mboxviewer.net/changelog/#v2-7-0-mac• Faster on large mailboxes: quicker searching, lower memory use, and no more UI freezes when opening very large messages or exporting. • More private: remote images (tracking pixels) are blocked more thoroughly, temporary files are cleaned up automatically, and new Settings let you clear your search history and index cache. • More accessible: full VoiceOver and keyboard support, adjustable message text size and font, better contrast, and the in-app language picker now lists all 18 languages. • More robust: handles malformed or oversized MBOX/EML files gracefully instead of freezing or crashing, and export/merge failures are now clearly reported. • HTML messages now show the sender header and quick actions (Export, Print, Share) at the top, just like plain-text messages.Fri, 03 Jul 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-6-5-machttps://mboxviewer.net/changelog/#v2-6-5-mac• New Full Headers view: see the complete header block (From, To, Cc, Date, Message-ID, Reply-To and more) in a clean, read-only pane. Pick it from the toolbar (Text / Headers / Raw) or from View → Full Headers (⌘2). Thanks to Verender Badial for the suggestion. • Eight new languages — Simplified Chinese, Traditional Chinese, Turkish, Swedish, Danish, Norwegian, Russian and European Portuguese — bringing the app to 18 languages.Thu, 18 Jun 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-6-0-machttps://mboxviewer.net/changelog/#v2-6-0-mac• Apple Mail export folders (.mbox packages) now open directly — no need to dig out the inner “mbox” file. • Mailbox files without an extension — like Thunderbird's INBOX or Sent — open directly, no renaming to .mbox required.Tue, 16 Jun 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-5-0-machttps://mboxviewer.net/changelog/#v2-5-0-mac• Email HTML is now sanitized before display — scripts, iframes and other active content are stripped, on top of the existing remote-image blocking. • Free-text search now looks inside message bodies too, not just subject and sender — so a plain word finds everything. • Hardened parsing of very large files so a message split across read buffers can never inflate the message count.Mon, 15 Jun 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-4-1-machttps://mboxviewer.net/changelog/#v2-4-1-mac• The About window now always shows the real installed version. • Added a «Redeem Code» button so you can use Mac App Store promo codes for the Pro upgrade.Tue, 02 Jun 2026 00:00:00 GMThttps://mboxviewer.net/changelog/#v2-4-0-machttps://mboxviewer.net/changelog/#v2-4-0-mac• Streamlined the App Store edition to a single lifetime Pro unlock.
