zimbra Received headers - email

Question

I installed Zimbra 9 Open Source build by Zextras on ubuntu 18. Everything works fine, except for the extra headers.
I try to remove received headers from sended mails (all headers like this: **Received: from... by ...**).
At first, I have like this:

In this headers I have 7 "Received" blocks
After this, I do in console:
> zmprov mcf zimbraMtaBlockedExtensionWarnRecipient FALSE
> zmprov mcf zimbraMtaHeaderChecks 'pcre:/opt/zimbra/conf/postfix_header_checks pcre:/opt/zimbra/conf/custom_header_checks'
and put into custom_header_checks this lines:
/X-Virus-Scanned/ IGNORE
/^X-Originating-IP:/ IGNORE
/^X-Mailer:/ IGNORE
/^Mime-Version:/ IGNORE
/^User-Agent:/ IGNORE
/^X-Sanitizer:/ IGNORE
/^X-Spam-Status:/ IGNORE
/^X-Spam-Level:/ IGNORE
/^X-MimeOLE:/ IGNORE
/^X-MSMail-Priority:/ IGNORE
/Message-Id:\s+<(.*?).JavaMail.zimbra#domain.org>/ REPLACE Message-Id: <$1#domain.org>
/^Received: (.*?)/ IGNORE
/^Received:/ IGNORE
After these actions I get this headers:

There are 4 blocks "Received" left.
How I can remove at least the last two?

Answer 1

Solved this issue:
In console:
zmlocalconfig -e postfix_header_checks="pcre:/opt/zimbra/conf/postfix_header_checks, pcre:/opt/zimbra/conf/custom_header_checks"
After in file /opt/zimbra/common/conf/master.cf.in from string:
-o receive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_address_mappings
remove no_header_body_checks
