Edit /etc/postfix/access and add entries like:

baduser@baddomain.com 550 No such user here

Then run the following command:

postmap /etc/postfix/access

Edit /etc/postfix/main.cf:

smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/access, {any other options already there...}

Then run the following command:

postfix reload

All fields marked with "*" are required.
