Claws Mail als Linux-Alternative zu Becky!

Aktualisiert am 18. Oktober 2026

Unser Fazit

Claws Mail is a strong replacement for Becky! for users who prioritize speed, low resource usage, and keyboard-driven workflows. It handles multiple accounts, POP3/IMAP, and local storage efficiently. The main trade-off is the lack of native HTML composition, which Becky! users may expect. If you rely heavily on graphical HTML editing, consider Thunderbird instead. For plain-text focused users or those who want a lightweight client that feels familiar to older Windows mail clients, Claws Mail is an excellent, stable choice with deep configurability.

Ihre Becky!-Dateien öffnen

Claws Mail can import emails from almost any other mail client, including Becky!. Since Becky! typically uses mbox or proprietary formats, you may need to convert your local mail folders to mbox first if they are not already in that format. Address books can be exported from Becky! as CSV or vCard and imported into Claws Mail. The interface is designed to be familiar, so the transition of data should be straightforward, though manual verification of folder structures is recommended.
