Version: 1.11.3 (using KDE 4.2.3)
Installed from: Ubuntu Packages
in kmail <1.11.3 I had a combined inbox/sentbox and used the wonderful threading feature of kmail to have threads of my mail conversations.
So I set my sent-box to be the same as my inbox - to spare me manual moving of mails.
kmail=1.11.3 is disabling the reply function in the sent-box. This is kind of reasonable - yet too restrictive to how I organize my mails. The reply function is now unavailable in my inbox.
For now setting a separate sent-box is doing the trick. But I really would love not to have to move mails from sent to inbox manually.
Why not enabling "reply" everywhere - the user will know what he is doing with a function like that.
