Question change server domain

[hoyohoyo]

Hello,
I have a Plesk vps server,
I configured a domain name domaine.fr for the default panel
The problem is when I send an email to an Outlook address it goes into spam

I look at the sources and I see that the default domain and that of my provider

How to change the domain of the server?

spf & dkim ok

Authentication-Results: spf=pass (sender IP is XX.171.167.XXX) smtp.mailfrom=xxxxerver.fr; live.fr; dkim=pass (signature was verified) header.d=xxxxver.fr;live.fr; dmarc=pass action=none header.from=xxxxxrver.fr;compauth=pass reason=100 Received-SPF: Pass (protection.outlook.com: domain of xxxxerver.fr designates XX.171.167.XXX as permitted sender) receiver=protection.outlook.com; client-ip=XX.171.167.XXX; helo=xxxxerver.fr;

But there is a problem here, the server has kept the domain of the provider, I would like to modify it, how?

Received: from vmi43xxxx.contaboserver.net (localhost.localdomain [127.0.0.1])

thx
