Just to find out why your server doesn't require authentication:
- Do you send directly from the server?
- Do you send from within a network which is specified in mynetworks in /etc/postfix/
- Do you send to a recipient who's on the server?

In all these cases you don't need to authenticate. You only need to authenticate if you want to send a mail from a remote PC to a recipient who's not on your server.
