     'Milter headers module' Document says as following.
     --------------------------------------------------------------------
     --
     remove_upstream_spam_flag (1.7.1+)
     Set false to keep pre-existing spam flag added by an upstream spam
     filter (default true). Enables remove-spam-flag.

     So if the message already have 'X-Spam' header when it arrived, it
     should be removed by Rspamd on my home server. But
     >     SPAM_FLAG(0.00)[];
     This seems to indicate that Rspamd detected 'X-Spam' header in the
     message in question. Then is it means that actual behavior of Rspamd
     is different from the one described in document and 'X-Spam' header
     added by upstream isn't removed by default?

   I do apologize.  I misread the score on your email as 97, I missed the
   negative.
   You're right, it shouldn't be adding a header.
   I agree with the previous poster, most probably the email already has
   that header added.
