That empty Content-Transfer-Encoding is incorrect.  It is most likely  
causing the parsing code on the IMAP server to incorrectly identify  
all the parts in the forwarded message.

Note that this is NOT an issue that can be fixed in imp.  We determine  
the structure of a message via the IMAP BODYSTRUCTURE command.  If  
that command is giving us incorrect information, there is nothing we  
can do about it.

In short, that e-mailer (Sun Messenger Express) is sending broken MIME  
messages.
