      Description

      I have a file called test.txt, containing only:
      Date: 06/25/2014 15:54:19
      And some more text I am writing. This will
      be detected as rfc822

      This file is detected and parsed as message/rfc822.
      I think the magic rule on "Date: " is too strong and it should have detected only as plain/text file. It looks to me like the reverse of https://issues.apache.org/jira/browse/TIKA-879

      We noticed this issue, because we have a large log file, which has many lines with Date, Log level and Message which is parsed as message/rfc822 (only because it starts with "Date:") and which throws
      StackOverflowError in the end.

      Is there some workaround to make this rule weaker ? through configuration ?
      We use DefaultParser and everything default. We use tika in 1.11 version, but we tried also with tika 1.16 and we saw the same StackOverflowError (which probably again happened because it was parsed as a rc822 type).
      The only workaround that I found was to add

      custom-mimetypes.xml like this
      <mime-type type="text/plain">
      <magic priority="70">
      <match value="Date:" type="string" offset="0"/>
      </magic>
      </mime-type>
      Would you recomend some other workaround to make sure the file does not get parsed as rfc822 ?
      And I have another question: can this custom-mimetypes.xml be specified from an external location?

      Many thanks.
