Open up Netscape Navigator and click on Options and then select Mail & News Preferences.

You now need to click on the Servers tab and enter in the following information:

Outgoing Mail (SMTP) Server: smtp.syd.fl.net.au
Incoming Mail (POP3) Server: pop.syd.fl.net.au
POP3 User Name: Your Username
News (NNTP) Server: news.fl.net.au

Any other options you may see here on this screen, you leave them as they are. There is NO need to modify any of them except the ones explicitly mentioned above.

Now, click on the Identity tab button at the top. You now need to enter in the following information as shown below:

Your Name: Obviously you place your name in this field. This is your real name NOT your username.
Your Email: username@fl.net.au - Replace username with YOUR username.
Reply-to-Address: username@fl.net.au

Once you have done all of these, your Netscape Mail is now configured to be used.
