I think a plugin would be possible, since it's possible to add  
dynamically more FETCH handlers using imap_fetch_handlers_register().  
With v1.1 this is even easier because you can use lib-mail/message- 
decoder.h to have Dovecot decode the base64/qp parts. Hmm. Although it  
forces translating charset to UTF-8, which isn't wanted with BINARY. I  
guess that part could have been made optional in the API..
