Jan Kundrát <j...@kde.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |NOT A BUG Status|REPORTED |RESOLVED --- Comment #1 from Jan Kundrát <j...@kde.org> --- Trojita uses Qt which uses OpenSSL as the TLS backend, and by default I believe it's going to use systemwide crypto policies. The error that you're getting comes back from OpenSSL, and unless I'm mistaken, it means that your IMAP server is using a crypto configuration that your operating system considers to be too weak. And indeed: $ openssl s_client -connect imaps.bluewin.ch:993 ... Server Temp Key: DH, 1024 bits ... That has considered insecure in Fedora's config since Fedora 33: https://fedoraproject.org/wiki/Changes/StrongCryptoSettings2 My suggestion is to report this to your e-mail provider. As a workaround, you might want relaxing the crypto preferences (see that Fedora page for help). -- You are receiving this mail because: You are watching all bug changes.
