STEPS TO REPRODUCE 1. Create a message and click in "Send" OBSERVED RESULT Messages stays in "pending to send" (sorry, I'm translating from my Spanish version, so not the exact folder name) EXPECTED RESULT To send immediately message (as always) SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20220807 KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 Kernel Version: 5.18.15-1-default (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-9700K CPU @ 3.60GHz Memory: 15.5 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 2060/PCIe/SSE2 ADDITIONAL INFORMATION When I launch kmail from console and in context menu over "pending to send" I select "Send messages in queue" after 5 or 10 seconds appear message "org.kde.pim.mailtransportakonadi: Item doesn't have DispatchModeAttribute." for each pending message. Meanwhile, after a lot of work trying to find a workaround, I needed to install Thunderbird, that as I guessed, have no problem sending messages.
