Description

MBOX file doesn't get recognized via "magic detection" mechanism as "application/mbox", but wrongly as "text/html".

Workaround for this in Tika 1.13 is achieved by placing following in custom-mimetypes.xml, as suggested on mailing list (priority has to be larger than message/rfc822):
<mime-type type="application/mbox">
<magic priority="70">
<match value="From " type="string" offset="0"/>
</magic>
<glob pattern="*.mbox"/>
</mime-type>

Sample MBOX file is attached.
