            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-bugs at kde.org
          Reporter: kde at 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.
