Have you looked at the documentation at all?  Basic postfix 
configuration is quite easy!

$ man 5 postconf

You will find dozens of howtos and tutorials on the net, too.

Look at "mynetworks".

Look at "mydestination", maybe "virtual_*_domains".

at "smtpd_recipient_restrictions".

Ask again, if you have _specific_ problems.
