Yury Kats created TIKA-2688:
-------------------------------

             Summary: MBOX not recognized when unknown X-headers are present
                 Key: TIKA-2688
                 URL: https://issues.apache.org/jira/browse/TIKA-2688
             Project: Tika
          Issue Type: Bug
          Components: detector, mime
    Affects Versions: 1.18
            Reporter: Yury Kats


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"/>
         <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>

MBOX rule look 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).
