From what I recall it's also necessary to tell postfix to use SASL and where to look for those credentials: in main.cf: smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd and 'postmap /etc/postfix/sasl/sasl_passwd'But this is AFAIK only needed if you use a smarthost with login data. For open relays it's not needed (but I'm not sure whether a open relayis a good idea in general)
I think there's a third alternative: ISPs usually only allow "sent" mail from IP addresses within their own assigned range of numbers.
For example, I send mail via postfix-as-smarthost to my ISP, but don't use sasl.
