Version: (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages After upgrading to KDE 4.2 (from 3.5) the accounts settings of kmail vanished. As I have a pop3 account, I reconfigured the "receiving" account without problem, but I couldn't do the same in the "sending" account. Each time that I finished to complete the data in the smtp (server, user, password, etc) and click apply, there isn't any smtp account configured. I've tried to reinstall kmail (deleting all the data in .kde/share/apps/kmail and .kde/share/config/kmailrc) but nothing. When I try to send an email, obviusly kmail said that there is no sending account.
I also experience this, with exactly the same symptoms. I configure and SMTP server using the KMail configuration dialog, but then when I have finished there is nothing there in the sending-accounts list. This is using current KMail from the Ubuntu experimental repository, "deb http://ppa.launchpad.net/kubuntu-experimental/ubuntu intrepid main" (Current is best KMail for a long time, though, until this version message index display was so slow I couldn't use it, much better now, thanks to whoever fixed that!!! - but this problem means I still can't use it for now :( ) kmail --version shows: Qt: 4.4.3 KDE: 4.2.00 (KDE 4.2.0) KMail: 1.11.0
I've found that this bug is actually https://bugs.kde.org/show_bug.cgi?id=178058 Deleting the mailtransport file (I´m not on my computer now, so I can´t remember the location exactly, but is in the .kde folder) solves the problems. It seems to be a permission problems. *** This bug has been marked as a duplicate of bug 178058 ***
I have experienced the same problem. More precisely, it seems root has become the owner of file ~/.kde/share/config/maitransports, probably during some upgrade.
