Bug ID: 363531 Summary: TLS negotiation was unsuccessful Product: kmail2 Version: 5.1.3 Platform: Fedora RPMs OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: crypto Assignee: kdepim-b...@kde.org Reporter: k...@sedrubal.de I want to send a mail using SMTP with STARTTLS. With other programs (thunderbird, k9mail) there is not problem but kmail complains about a unsuccessful TLS negotiation. First warning dialogue: > The server failed the authenticity check (mail.rommel.stw.uni-erlangen.de). > > The certificate authority's certificate is invalid > The certificate cannot be verified for internal reasons Clicking on "Continue" works, clicking on "Details" displays the expected TLS certificate (I thinkt everything is correct). Clicking on "Cancel" displays: > Your SMTP server claims to support TLS, but negotiation was unsuccessful. > You can disable TLS in the SMTP account settings dialog. Is there a way to debug such issues (displaying the conversation between kmail and the SMTP Server)? The server is exim4. -- You are receiving this mail because: You are watching all bug changes.
