TIKA mistakes RTF message for email

an RTF message similar to the below is wrongly detected as message/rfc822 and handed off to the email parser even though it starts with an RTF tag. This is likely due to the presence of "Sent: " and "Received: " email-header-like lines. I guess that the detection phase tries email first and that accepts it, rather than getting a confidence score from each detector/parser and then choosing the one with the highest score.

Can we tell TIKA from python to use a specific parser (RTF in this case) since we know the message type? Rather than detecting at all? If not, can this be done on the JAVA side? Note that we are running with an external java server, so tika-python is in client only mode.

Thanks.

TIKA server returns these metadata:

realJson = [{
        "Content-Type": "message/rfc822",
        "Message:Raw-Header:Received": " (4): 1\\par",
        "Message:Raw-Header:Sent": "(4):\\par",
        "Message:Raw-Header:[host": "port\u003domitted,accessKeyId\xxx] Sent/Received sequence number is 4/4.\\par",
        "X-Parsed-By": ["org.apache.tika.parser.DefaultParser", "org.apache.tika.parser.mail.RFC822Parser"],
        "X-TIKA:embedded_depth": "0",
        "X-TIKA:parse_time_millis": "5"
    }
]
