Description

I have a number of email messages that contain other email messages as attachments (with multiple levels of nesting).

The email attachments are parts with "Content-Type: message/rfc822" but are not being recognized as such.

Attached is an example email, with the multiple levels of attachments:

• Subject: Test email within email
  • Subject: Email within email test
    • Subject: Stand-up today

 

I would like to see 3 separate emails parsed out (top level, 1st level attached email, 2nd level attached email), but I only get 1 email and 1 unnamed text attachment:

$ java -jar tika-app-1.18.jar -m -J nested.eml | python -m json.tool
