The reason I ask is that there are many aging bugs for this application that haven't been acknowledged yet, let alone dealt with.

For instance, when is something going to be done about getting "local folders" to be usable? Automatic filing of postings last worked in version 0.10.4 and I think drag-and-drop or any other form of copying to local folders probably failed around the same time.

The daft thing is that importing of local folders and also their creation is still functioning. So what's the point of that when they are unusable?

From the deafening silence, I guess the answer is "no". Back to Thunderbird for me then.

The "deafening silence" is due to us not knowing about this subject. You may wish to contact the KDE PIM Users mailing list ( kdepim-users@kde.org ) who may have more information on the subject.
