    RFC 2821 (which indeed asks servers to support the 8BITMIME extension, using
    SHOULD) is "only" 4 year old (RFC 1652 did not require server support.)
    Also the renewing of softwares in this area is _very_ slow (why changing
    something that just works?)
    And some mail administrators are quite angry when you ask them to update
    their softwares, but more importantly the vast majority of them quite simply
    do not attend your requests (because of the excess of junk mail that is
    floating around.)

    I guess RFC 2821 did the first step, which was to include the SHOULD. Its
    revision will then put MUST (thus requiring effective upgrades), and it
    would be the next revision after that which could allow a client (MUA or
    MTA) to send 8-bit material without proper workaround if the server is not
    able to deal with it... Only then you could say the castrating servers are
