There is a difference between a sub-part and the last part which can 
have a trailing epilogue.  See below.

I'm no expert, but it looks OK to me.  The spec says:

-------------------------------------------------------------
multipart-body := preamble 1*encapsulation close-delimiter epilogue

encapsulation := delimiter body-part CRLF

delimiter := "--" boundary CRLF ; taken from Content-Type field.
                                ; There must be no space
                                ; between "--" and boundary.

close-delimiter := "--" boundary "--" CRLF ; Again, no space by "--",

preamble := discard-text   ;  to  be  ignored upon receipt.

epilogue := discard-text   ;  to  be  ignored upon receipt.

discard-text := *(*text CRLF)

body-part := <"message" as defined in RFC 822,
          with all header fields optional, and with the
          specified delimiter not occurring anywhere in
          the message body, either on a line by itself
          or as a substring anywhere.  Note that the
          semantics of a part differ from the semantics
          of a message, as described in the text.>
-------------------------------------------------------------

The part you are questioning would constitute the epilogue the 
way I read it.

Therefore, my guess is that the problem is with your mail client, not 
the message.

For help on using this list (especially unsubscribing), send a message to
"gnu-win32-request AT cygnus DOT com" with one line of text: "help".
