--- Comment #55 from Christoph Feck <cf...@kde.org> --- It is a security reason. You could receive an HTML mail that looks like a plain text mail, and with HTML you have the ability to embed malicious links everywhere. If you have no way to see that the message is actually an HTML message, i.e. _outside_ the message viewer, you could click those links without being aware that they link to sites that you don't see in the text. I agree, though, that there could be other possibilities to inform the user of HTML mails, e.g. via statusbar or toolbar icons. But if they are too non-obvious, you could miss them. In other words, if the security bar is in your face, it actually works as intended. Also, the message viewer doesn't know about other UI elements. If you find a different way that doesn't compromise security, please let us know.
