I have recently zypper dupped to opensuse 11.4 from 11.3. My only problem is I am unable to access my address book when I click <select> when sending a new message; only recent addresses show in the window that pops up. Even if I select <all> in the list of choices, only <recent addresses> show up. In the useful tips that appear upon opening K-mail it states that if I click on < folders> then < Mailing list management> I will be able to select and manage all of my address books. But when I click on <folders> the <mailing list management> is faded telling me that it is not enabled. My question is what must I do to enable the mailing list management to be enabled? I have enabled mailman with no help.
The problem is that the location at which KMail looks has changed. You need to make sure that the location which your default address book properties gives in Contacts is the same as the address in System settings>Personal information>KDE resources. I cannot tell you exactly how to do that because it was different in different users when I did this; so I had to do it differently for different users.
