Claws Mail, alternative Linux à The Bat!
Mis à jour le
Notre avis
Claws Mail is a solid replacement for The Bat! if you prioritize speed, local mail storage, and lightweight design over built-in calendar and advanced encryption tools. It handles multiple accounts, strong filtering, and offline access well, and its MH storage is reliable. However, it lacks native PGP and S/MIME support—plugins are required—and has no built-in calendar. It suits users who want a fast, keyboard-driven client and don’t mind setting up encryption separately. Not ideal for those relying heavily on integrated security or contact management.

- Lighter feature set out of the box, focused on simplicity over all-in-one design
- Smaller user base and less commercial support compared to The Bat!

Claws Mail can import mail from most common formats via its import tools, including mbox and MH. While there's no direct importer for The Bat!'s proprietary storage format, you can export messages from The Bat! to mbox or EML and then import them into Claws Mail. This process works reliably for messages, but filters, rules, and folder structures may need manual recreation. Contact and calendar data must be exported separately and re-imported if supported by plugins.

Does Claws Mail support PGP encryption?
Yes, but not out of the box. You need to install and configure the PGP plugin using GnuPG for signing and encrypting messages.
Can I use Claws Mail with HTML emails?
You can read HTML emails if the proper plugin is installed, but Claws Mail does not support composing HTML—only plain text.
Is calendar integration available?
Not natively. You can use the 'Calendar' plugin, but it's basic and not tightly integrated like in The Bat!.
