dovecot - Dec 2019 - About "received" header when using Dovecot proxy

Hello.

Sorry.
Since 2.3.9 was released, I installed it immediately and tried to set
"lmtp_add_received_header" to "no".
But it seems different from what I wanted to do.
The following is my configuration file.
Please let me know if there are any other configuration files that need to be
listed.
Is there any way to avoid adding it to the ?received? header?

----- 20-submission.conf -----
submission_client_workarounds = whitespace-before-path mailbox-for-path

protocol submission {
  passdb {
    driver = static
    args = proxy=y host=smtp.example.com nopassword=y
  }
}
--------------------

Best regards.

So... what did it do and what did you expect it to do?

Hello.

Sorry.
Organize and describe what I want to do.
There may be no unity, but please forgive me.
Also, I'm not good at English, so I'm sorry if it's difficult to
understand.

1. I had to create a proxy server for an external SMTP server (here,
?smtp.example.com? as an example).
So I decided to use Dovecot installed on my server (in this example,
?my-server.com?).
2. Therefore, the following settings were created.

----- /etc/dovecot/conf.d/10-auth.conf -----
auth_mechanisms = plain login cram-md5 apop
!include auth-static.conf.ext
--------------------

----- /etc/dovecot/conf.d/auth-static.conf.ext -----
passdb {
  driver = static
  args = proxy=y nopassword=y
  default_fields = destuser=%u nologin=y starttls=any-cert
}

userdb {
  driver = static
  args = uid=mail gid=mail /home=/dev/null
}
--------------------

----- /etc/dovecot/conf.d/10-ssl.conf -----
ssl = yes
ssl_cert = </etc/letsencrypt/live/my-server.com/fullchain.pem
ssl_key = </etc/letsencrypt/live/my-server.com/privkey.pem
--------------------

----- /etc/dovecot/conf.d/20-submission.conf -----
submission_client_workarounds = whitespace-before-path mailbox-for-path

protocol submission {
  passdb {
    driver = static
    args = proxy=y host=smtp.example.com nopassword=y
  }
}
--------------------

3. With the above settings, when my mailer connects to
"my-server.com", it can connect to "smtp.example.com" and
send / receive via SMTP.
4. However, in this case, the value of the mail header "received" will
be as follows.

Received: from my-server.com (my-server.com [<my-server.com IP address>])
...

I want the IP address of the sender (my computer here) to be displayed properly
in the contents of this "received" like this.

Received: from riku22.net (xxxxx.bbtec.net [126.125.xxx.xxx])


Is there any way?

Best regards.
