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.
