Since some time, I have to disable rich text editing every time I want to send a message. I think that earlier kmail versions had an option to compose plain text messages by default. Now I do not find such an option anymore. Am I am missing something? Interestingly, when replying to or forwarding a message, rich text editing is disabled. Would be great if you could add an option to enable/disable this by default (or point me to the place where I can configure this).
