Version: 2.0.89 (using KDE 4.5.85) OS: Linux The sorting of folders in the list in Kmail2 sorts the folders by alphabeth, but sepately for capital and small letters. This was different in Kmail1 and I believe it was better that way. At least for me having some folders with capital letters and some not has rather historic reasons (some software which created those folders did not allow otherwise) and not really a purpose. Reproducible: Always OS: Linux (i686) release 2.6.37-7-generic-pae Compiler: cc
Yes in kmail1 we didn't look at capital letters. Will look at soon if it's possible to fix it.
Fixed in master/4.7.1
