Y, will do. Results probably tomorrow.

This?

> When using {{DefaultDetector}} mime type for {{.eml}} files is different (you can test it on {{testRFC822}} and {{testRFC822_base64}} in {{tika-parsers/src/test/resources/test-documents/}}).
> Main reason for such behavior is that only magic detector is really works for such files. Even if you set {{CONTENT_TYPE}} in metadata or some {{.eml}} file name in {{RESOURCE_NAME_KEY}}.
> As I found {{MediaTypeRegistry.isSpecializationOf("message/rfc822", "text/plain")}} returns {{false}}, so detection by {{MimeTypes.detect(...)}} works only by magic.
