Sending mails using local server, not esternal SMTP

Hello, I'm probably a bit confused about configuring sending emails in Laravel... In the development environment everything works fine but, moving to the production environment, I have a configuration problem. In the development environment I had left the default configuration (STMP, with mailgun... I don't understand about this: is mailgun used for free???). Moving on to the production server, I would like to configure the system to send emails using my local system, not an external SMTP. The machine obviously has its own SSL certificate and sending from PHP, using the classic mail() function, without particular configurations, works correctly. Could you please tell me how to configure Laravel? I tried to set both sendmail and SMTP (putting the local server) but I always get the same error:

Unable to connect with STARTTLS: stream_socket_enable_crypto(): Peer certificate CN=<my_domain>' (obviously it doesn't say my_domain but my domain name) did not match expected CN=localhost'

Can you help me?

My config/mail.php (I don't understand if this is important or if the settings present in the .env override these):
