If you look at that last uuid, you see:

--uuid:0b4207bc-f374-4c94-a6c7-c6762711b57b--

Note the last two "--" on the end.   That's marking the end of the message, 
not the header for the next part.   With mime, you need both open and 
closing boundaries.

To do what you want, you could add an interceptor VERY VERY early in the out 
chain that can detect if somehow if mime will be used or not and call 
messge.setProperty("mtom-enabled", "false") 

which would then disable all the mtom processing for that message.
