Stefano Bagnara resolved MIME4J-177.
------------------------------------

    Resolution: Fixed

At least for the preamble this is resolved and my dkim issue is fixed. I had no time to deeply study the epilogue status.

> The token stream sends T_PREAMBLE tokens even when there is no preamble in the message making impossible to distinguish between messages with no preamble and messages with an empty preamble.
> T_PREAMBLE should be called only when a preamble exists:
> The rfc define multipart-body as:
>      multipart-body := [preamble CRLF]
>                        dash-boundary transport-padding CRLF
>                        body-part *encapsulation
>                        close-delimiter transport-padding
>                        [CRLF epilogue] 
> So preamble is optional (if the is a CRLF before the first boundary then you have a preamble).
