            Bug ID: 322383
           Summary: IMAP resource hangs without error message when server
                    supports SSLv3 only
    Classification: Unclassified
           Product: Akonadi
           Version: 4.10
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: IMAP resource
          Assignee: ervin at kde.org
          Reporter: trouble at garni.ch
                CC: kdepim-bugs at kde.org, vkrause at kde.org

Upon connecting to a Lotus Notes/Domino IMAP server via SSL, the IMAP resource
simply does nothing, not even update the status message. The IMAP resource
status message stays at whatever value it had before trying to connect to the
server, and nothing more happens, no CPU usage, no fetching. IMAP resources DID
work with KDE 4.8. It stopped working after the upgrade.

ssldump registers connection attempts in some intervals, but connections are
dropped immediately after handshake. Further investigation shows that the
server only supports SSLv3, not TLS1 (i.e., "openssl s_client ... -ssl3" works,
"... -tls1" doesn't). When proxying the connection with stunnel configured as
"sslVersion = SSLv3", IMAP works. stunnel fails just the same when leaving out
that option.


Reproducible: Always

Steps to Reproduce:
1. Configure an akonadi IMAP resource to access an SSLv3-only IMAP server
2. Look at nothing at all happening
3. Profit?

Actual Results:  
No user-visible reaction at all.

Expected Results:  
At least some kind of error message. Ideally, a working IMAP resource.
