> 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!
