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

["Yury Kats (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-2680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16528296#comment-16528296 ] 

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

This appears to be due to the fact that mime4j treats an attached email as "new message" (correctly) and not as a "part" of the original email.

MailContentHandler#body is not being called. Instead MailContentHandler#startMessage is called, and thus MailContentHandler does not do any recursive parsing/extraction. The parts of the nested message are treated as parts of the original.

> 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:
