Hello,
I need your help.

I am using CentOS 5.0 and kmail many years. Now I am reinstall my system with CentOS6.4, want to using kmail.

Get email from pop3 server I get:
Could not read file Invalid response from server : ".

Reading allready local saved email I get Akonadi error only one time:
Akonadi control process not registered at D-Bus.

Any ideas, many thanks in in advance, Robert.

What version of KDE PIM are you using, given that for sure CentOS is a bit behind the newest versions?

Hi, CentOS 6.4 use this version:

# rpm -qa| grep kde | grep pim
kdepim-libs-4.3.4-6.el6.i686
kdepimlibs-akonadi-4.3.4-4.el6.i686
kdepim-runtime-4.3.4-5.el6.i686
kdepim-4.3.4-6.el6.i686
kdepim-runtime-libs-4.3.4-5.el6.i686
kdepimlibs-4.3.4-4.el6.i686

This version is not yet Akonadi-based (it uses the old approach) and it is unfortunately very old, thus a bit more difficult to debug for me (I'm on 4.11). Nevertheless, do you get the same error if you create a new user account with the same POP account?

Hi einar,
many thanks for your reply. I get a new error : Unable to complete LIST operation.
@CentOS
I will forget CentOS. I don't have any understanding, why after a new installation of CentOS 6.4, this software is running bad. I only use yum update. This kmail error occured after a yum update.

I will try to install ubuntu.
Thanks, Robert.
