Review Comment:
@gchauvet this is not correct as per rfc1341 (see please
https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html):
```
Overall, the body of a multipart entity may be specified as follows:
multipart-body := preamble 1*encapsulation
close-delimiter epilogue
encapsulation := delimiter CRLF body-part
delimiter := CRLF "--" boundary ; taken from Content-Type
field.
; when content-type is
multipart
; There must be no space
; between "--" and boundary.
close-delimiter := delimiter "--" ; Again, no space before
"--"
preamble := *text ; to be ignored upon
receipt.
epilogue := *text ; to be ignored upon
receipt.
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 element in question is
```
close-delimiter := delimiter "--" ; Again, no space before
```
