Could you take one mail from the mail queue and try to find its log entries in /var/log/maillog, please? What do the log entries say? There must be some, else the mail could not wait in the queue.

Is port 25 open on your server and in the firewall of your data center? As far as I know, OVH may need an extra setting in your data center backend to open port 25. If that is not opened, mails cannot be sent.

Hm.. ok thanks, i have open the port in my server, but nothing again, after a nmap scan, the port is filtered so i have send a ticket to OVH for open the port, i don't have any option in my backoffice for open the port on my dedicated :/

Even if you have the option, All cloud service providers block all sending ports by default to protect thire IP Pools from possible abuse from any customer. you must request them to open it, they may possibly request you to attach your server IP with rDNS/TXT record to your domain name to detect email abuse.

Yes indeed that was it, they opened the port after my ticket, thanks to you both, it's solved suddenly
