Claws Mail, alternative Linux à Windows Mail
Mis à jour le
Notre avis
Claws Mail is a strong replacement for Windows Mail if you value speed and keyboard control over visual polish. It handles multiple IMAP/POP3 accounts, offers powerful search, and supports calendar via plugins. The interface is dense and functional rather than modern, which may feel dated to some. It lacks native HTML composition, relying on external editors for plain text. If you want a lightweight, stable client that respects your time and doesn't bloat your system, this is a solid choice. Avoid it if you need a sleek, mouse-driven experience or heavy HTML email creation.

Ouvrir vos fichiers Windows Mail
Windows Mail typically uses EML files for individual messages and may store data in proprietary formats. Claws Mail can import EML files directly into its MH format. It also supports importing from other clients like Thunderbird or Outlook. If your Windows Mail data is in a non-standard container, you may need to export individual messages first. Direct .pst import is not native but possible via conversion tools.
