Message Source not configured properly?

Hi All, First off, just wanted to say what a great mail package RoundCube is. Its fully featured, looks great, and simply is an amazing package!

Sadly, I have a problem that is keeping me from using it. When sending mail it seems that the message body somehow gets mixed with the header (or vice versa).

I've tried sending mails to gmail, and my work account. In both cases, the message source looks like so:
