If this message is completely broken then it seems that there are many  
such messages being sent. I say this because this message reads  
perfectly when viewed by Sylpheed, Gmail, and Android AquaMail. These  
clients (the only ones I have to test with) parse whatever this  
message contains and display the embedded html perfectly. In order to  
do that they must be programmed to recognize the format and either  
completely understand it or be able to fix it on the fly. Why would a  
programmer do that unless there were enough of these type of messages  
to warrant the extra work involved? My conclusion is that this message  
isn't broken. But as to why imp isn't able to display it, no matter  
what it is, I can't imagine.
