see <565A0E05A5407BFAB0BC0189@???> from earlier
today, which suggests,

     # header field name with 8-bit char
    deny    message = Your message contains invalid headers
            log_message = message header 8-bit
            condition = ${if match{$message_headers}{(?im)^[^: ]*[\x80-\xFF]+[^:]*:}{1}{0}}
