It tells you what the problem is:

Code:

Relay access denied

Make sure:

Code:

smtpd_recipient_restrictions = permit_sasl_authenticated

is NOT commented out in: /etc/postfix/main.cf

(Change 'mydomain.com' to whatever yours is, also change 'my.servers.ip.address' to your server's external IP)

You will also need to remove the SSL certificate stuff if you are not using one.

Some settings I am sure are different as I am using a Let's Encrypt certificate for my mail.mydomain.com
