--- Comment #2 from Laurent Montel <mon...@kde.org> --- I think it's a draft which was created with another mailtransport id. I think that you have create this email with another instance of kmail or you reinstall it etc. This warning is displaying when "X-KMail-Transport: <value>" in unknown. it's normal that it will send correctly as it will fallback to new mailtransport id. -- You are receiving this mail because: You are watching all bug changes.
