You've deleted bottom line (...-----------------...) which divides
mail(header + body) from this chatter.
String "I think it should not be.", is just a part of mail, that is, it's body.
Completely irrelevant here.

Yes I know that.Simply haven't knew how to formulate this mail comand line.
I send mail by firstly typing: /usr/local/sbin/sendmail -G -i -f
r...@example1.com j...@example2.com
Then I hit enter. Then I paste mail(header + body).
Then I hit:

Postfix has already received relayed mail and added first Received: header
Then it came into my filter.
After filter has done it's job, it send it back to potfix by using
/usr/local/sbin/sendmail, which adds ANOTHER Received: header
Nothing should touch or add anything to mail header or it's body,
after filter has done it's job!

That is not an option

I've gave you exact example of how I use sendmail command
You've also deleted key part here.
If that sendmail command is being executed as a ROOT, then mail ends
up in target mailbox as I showed.

BUT, after I've created user "filter" and set it as owner and
executioner of filter proces in master.cf
In target mailbox I get mail like this:

from (unknown sender)
to (no subject)
Received: by khole.example1.com (Postfix, from userid 1003)
        id 27A1711429; Mon, 23 Aug 2009 19:29:36 +0200 (CEST)

Everything is being stripped!!!
Only that has been left is a SECOND header added by sendmail command.

In mail log I see:
postfix/cleanup[17465]: C473511429: message-id=<>

It does it? But NOT for root user
