DESCRIPTION
       Perform various tests against MIME structure and body.
       has_check_for_ascii_text_illegal
           Adds capability check for "if can()" for
           check_for_ascii_text_illegal
       check_for_ascii_text_illegal
           If a MIME part claims to be text/plain or
           text/plain;charset=us-ascii and the Content-Transfer-Encoding is
           7bit (either explicitly or by default), then we should enforce the
           actual text being only TAB, NL, SPACE through TILDE, i.e. all 7bit
           characters excluding NO-WS-CTL (per RFC-2822).
           All mainstream MTA's get this right.
       has_check_abundant_unicode_ratio
           Adds capability check for "if can()" for
           check_abundant_unicode_ratio
       check_abundant_unicode_ratio
           A MIME part claiming to be text/plain and containing Unicode
           characters must be encoded as quoted-printable or base64, or use
           UTF data coding (typically with 8bit encoding).  Any message in
           7bit or 8bit encoding containing (HTML) Unicode entities will not
           render them as Unicode, but literally.
           Thus a few such sequences might occur on a mailing list of
           developers discussing such characters, but a message with a high
           density of such characters is likely spam.
       has_check_qp_ratio
           Adds capability check for "if can()" for check_qp_ratio
       check_qp_ratio
           Takes a min ratio to use in eval to see if there is an spamminess
           to the ratio of quoted printable to total bytes in an email.
