            Bug ID: 356217
           Summary: TLS handshake fails with "no shared cipher".
           Product: kmail2
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: Bjorn at xn--rombobjrn-67a.se

As Claws Mail in Fedora 23 crashes on PGP-signed email, I figured I'd check
whether Kmail is usable again. But Kmail seems to be unable to complete a TLS
handshake. It appears to get stuck forever trying to open a mail folder, while
the IMAP server logs this error message several times per second:

dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>,
rip=[...], lip=[...], TLS handshaking: SSL_accept() failed: error:1408A0C1:SSL
routines:SSL3_GET_CLIENT_HELLO:no shared cipher,
session=<GQMVo+AlwAAgAlfjF18AcgAAAAAAAAAB>

"no shared cipher" seems to be the key. The server has a list of strong modern
ciphersuites. How do I get at Kmail's ciphersuite list?

Reproducible: Always
