The detect api and rfc822

[Ramachandran, Karthik]

Hi,

I'm trying to detect an email with Tika's auto dectet api. However I keep 
getting back an "application/octet-stream" as the mime type:

    Tika tika = new Tika();
    InputStream document = new InputStream(new File(...));

    String mimeType = tika.detect(document);

Thanks,

Karthik
