In the current MIME spec. the following paragraph is included
discussing message/partial reassembly:
(2) Only those header fields in the enclosed message which start
with "Content-" and Message-ID", "Encrypted", and "MIME-Version"
must be appended, in order, to the header fields of the new
message. Any header fields in the enclosed message which do not
start with "Content-" (except for "Message-ID", "Encrypted", and
"MIME-Version") will be ignored.
(on Page 40)
Why is this restriction made? Why should the other headers be
ignored and why does the "order" of the headers have to be
maintained??
