[jira] [Commented] (TIKA-2680) Email attachments to an email are not extracted

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/TIKA-2680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16535351#comment-16535351 ]

Yury Kats commented on TIKA-2680:
---------------------------------

Indeed, the first embedded rfc822 is not an attachment. I believe this is because it's an Exchange journaled email, see the presence of X-MS-Journal-Report header at the very top.

> 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:
