  8. The existing "accept_8bitmime" option now defaults to true.  This means
     that Exim is deliberately not strictly RFC compliant.  We're following
     Dan Bernstein's advice in http://cr.yp.to/smtp/8bitmime.html by default.
     Those who disagree, or know that they are talking to mail servers that,
     even today, are not 8-bit clean, need to turn off this option.
