instead of googling, simply use the postfix documentation that came with 
the software.  your goal is accomplished by implementing smtp auth, 
which postfix offers by way of sasl authentication.  to that end, this 
is documented in SASL_README.  i would recommend that you use dovecot 
rather than cyrus for sasl.  while SASL_README of course includes a fair 
amount of documentation for the associated sasl software, you'll likely 
also want to reference the documentation provided with that software as 
well.

on a related note, as this is for humans to send mail from their mail 
clients, you'll want to configure a proper submission [port 587] 
service.  see the commented example in master.cf for a starting point. 
smtp auth should be offered only via the submission service, and not via 
mx service [port 25].  additionally, encryption should be required for 
submission traffic.
