           Summary: KMail 1.13.6 IMAP with MS Exchange over STARTTLS does
                    not fetch new mails any more.
           Product: kmail
           Version: 1.13.6
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: IMAP
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: dyle at dyle.org


Version:           1.13.6 (using KDE 4.6.0) 
OS:                Linux

KMail was working since some KDE 3.x back to some KDE 4.5.x version without any
troubles. After the last updates it stopped working with the MS Exchange on
IMAP via STARTTLS.

KMail remained silent for a number of days after the recent updates. This was
good at first, but then I got pretty anxious ... and throughout the Outlook
Webfrontend I figured out I missed nearly 50 mails.

Testing the connection using openssl s_client -crlf -starttls imap -connect
SERVER:PORT worked properly. I could login and query my inbox.

Kmail just remained silent. It does not fetch any emails any longer and I don't
know why. The "Checking account ..." in the flashes and after I accepted the
certificate "Forever" (each time yet) it goes to "timed out" with 100%.

A newly setup Thunderbird with the same config data works well out of the box.

Coincident: suddenly kmail asks my confirmation about the SSL certifcate each
time. It does not care if I accepted it "forever".

Please help! Thank you.

Reproducible: Always

Steps to Reproduce:
Click on "Check Mail"

KMail should accept the certicate, when I approved it (once and for good). And
then it should query the mails on the IMAP MS Exchange via STARTTLS.

Actual Results:  
KMail says "timed out".

Expected Results:  
KMail should fetch all mails stored at the IMAP server.

KMail was working properly for at least 2 years in this configuration. However
new release does not work here. :(
