The reason most likely isn't your Postfix, but the ISP blocking outbound connections to port 25/tcp. The rationale behind this is to prevent home computer bots from sending spam. Use submission (SMTP with authentication enforced on port 587/tcp) instead. You should use authentication (and encrypted connections) anyway, if you want to relay through your MTA from anywhere in the world.
