[jira] [Commented] (TIKA-2688) MBOX not recognized when unknown
X-headers are present
[ https://issues.apache.org/jira/browse/TIKA-2688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16548496#comment-16548496 ]
Yury Kats commented on TIKA-2688:
---------------------------------
To be consistent with TIKA-2578, I would suggest to change the mbox magic to
{noformat}
<magic priority="70">
<match value="From " type="string" offset="0">
<match value="\nFrom: " type="string" offset="32:256"/>
<match value="\nDate: " type="string" offset="32:256"/>
<match value="\nSubject: " type="string" offset="32:256"/>
<match value="\nDelivered-To: " type="string" offset="32:256"/>
<match value="\nReceived: by " type="string" offset="32:256"/>
<match value="\nReceived: via " type="string" offset="32:256"/>
<match value="\nReceived: from " type="string" offset="32:256"/>
<match value="\nMime-Version: " type="string" offset="32:256"/>
<match value="X-" type="stringignorecase" offset="32:256">
<match value="\nFrom: " type="string" offset="32:8192"/>
<match value="\nDate: " type="string" offset="32:8192"/>
<match value="\nSubject: " type="string" offset="32:8192"/>

<match value="\nReceived: from " type="string" offset="32:8192"/>
<match value="\nMime-Version: " type="string" offset="32:8192"/>
</match>
</match>
</magic>
{noformat}

> Issue Type: Bug
> Components: detector, mime
> Affects Versions: 1.18
> Reporter: Yury Kats
> Priority: Major
>
> This is a spin off from TIKA-2578
> I have mbox files that are not being recognized as such because they have X- headers at the top.
> Current config:
> {noformat}
> <mime-type type="application/mbox">
> <!-- MBOX files start with "From [sender] [date]" -->
> <!-- To avoid false matches, check for other headers after that -->
> <magic priority="70">
> <match value="From " type="string" offset="0">
> <match value="\nFrom: " type="string" offset="32:256"/>
> <match value="\nDate: " type="string" offset="32:256"/>

> MBOX rule looks for additional headers only in the first 256 bytes, which is not enough when X- headers are present.
> Side-note: prior to 1.17 such mbox was detected as text/plain. As of 1.17 it is detected as message/rfc822 (due to TIKA-2594 that added a rule for Message-ID being present in the first 1000 bytes). Neither is correct!
