> Key: TIKA-2578
> URL: https://issues.apache.org/jira/browse/TIKA-2578
> Project: Tika
> Issue Type: Bug
> Components: detector, mime
> Affects Versions: 1.17, 1.18, 2.0.0
> Reporter: Andreas Meier
> Assignee: Tim Allison
> Priority: Major
> Fix For: 1.18, 2.0.0
>
> Attachments: testRFC822_with_leading_x_header
>
>
> Found some mails with leading X-headers.
> These mails are recognized as text/plain.
> One example is CISCOs IronPort, which might add "X-IronPort-AV" to the
> beginning of mails.
> Therefore I would like to discuss if and how TIKA shall handle these cases.
> In my opinion TIKA should try to detect files with x-headers and preprocess
> them to get a valid mail.
> Suggestion:
> {code:xml}
> <mime-type type="text/x-tika-x-header">
> <magic priority="50">
> <match value="X-" type="string" offset="0">
> <match value="Message-ID:" type="string" offset="0:8192"/>
> <match value="From:" type="stringignorecase" offset="0:8192"/>
> <match value="To:" type="stringignorecase" offset="0:8192"/>
> <match value="Subject:" type="string" offset="0:8192"/>
> <match value="MIME-Version:" type="stringignorecase" offset="0:8192"/>
> </match>
> </magic>
> <sub-class-of type="text/x-tika-text-based-message"/>
> </mime-type>
> {code}
> See also: [RFC6648|https://tools.ietf.org/html/rfc6648]
> Attached an example file.
