Claws Mail, alternative Linux à Eudora

Mis à jour le 18 octobre 2026

Notre avis

Claws Mail can serve as a solid replacement for Eudona for users who need a fast, keyboard‑friendly client with solid IMAP/POP3 support, local storage, filtering and threading. It lacks a built‑in HTML composer, so anyone who relied on sending formatted mail will need a workaround. For users who valued a simple, native‑Linux client and are comfortable with plain‑text or external editors, Claws Mail is a good fit; power users who need extensive HTML handling may find it limiting.

Ce qui change

Claws Mail stores mail in MH format by default, not mbox used by Eudora
No native HTML composer; HTML reading requires a plugin
Eudora’s integrated calendar and rich‑text editor are missing
Claws Mail relies on external editors for composing, unlike Eudora’s built‑in editor
Eudora’s Windows‑only UI conventions differ from Claws Mail’s GTK interface

Ouvrir vos fichiers Eudora

Claws Mail can import mail from most other clients, including mbox files, which covers the bulk of Eudora's stored messages. Direct import of Eudora's proprietary address book format is not documented, so you may need to export contacts to a generic CSV or vCard format from Eudora first. Exporting from Claws Mail back to Eudora is possible via mbox export, but round‑tripping is not guaranteed.

Passer de Eudora à Claws Mail, étape par étape

Export Eudora mail folders to mbox files (File → Export).
Copy the mbox files to your Linux home directory.
In Claws Mail, use File → Import → Import mbox to bring the messages into the MH folder tree.
Export Eudora contacts to CSV or vCard, then import them via Claws Mail's Address Book → Import.
Configure your IMAP/POP3 accounts in Claws Mail, matching the same server settings.
Test sending a plain‑text message; if you need HTML, install the htmlview plugin or use an external editor.
