I've been trying to switch to kmail since some time now but I'm not able to do it because despite having very advance interface, its basic features are not properly working. I just installed opensuse 12.2 32 bit and updated to kde 4.9.1 and configure gmail disconnected imap account. I tested several features and configured it as per my needs but encountered very annoying bug. The status of mails is not reflected on server. Instead of deleting emails, they're being archived on gmail. Some mails stay unread. Please note that gmail settings seem fine as I've been using evolution client with same settings without any problem. I also try refreshing folders and empty trash but seems changes are not reflected in gmail. I really wish to switch to kmail because of the flexible features it is offering but encountering such basic issues is stopping me from using it effectively. Reproducible: Always
This appears to be fixed in 4.10
