The message contains a 0xbb character that wallace is choking on.

I've had some similar errors, and just for laughs changed these 
characters into something else using hexedit, after which the mails went 
through without problems. For now, I have disabled wallace on my Kolab 
instance.

This is bug https://issues.kolab.org/show_bug.cgi?id=1627.
