You need to set the variable
'relayhost = [nameofsmarthostserver.tld]' in you main.cf file.
Then create the file /etc/postfix/sasl/sasl_passwd; so,
inside that file specify the relayhost details again:
obviously use your own login credentials for the remote server there.
Once you have done that, 'postfix reload' and 'postfix check' to check for errors.
