/etc/postfix/postfix.cw 

You need to create this file yourself.   If you only have the one domain,
it's not necessary, but that means your machine always must be identified,
email-wise, as $mydomain, whatever that is.  Better to list all possible
names (host, host.domain, domain ...) in this file.

Ok, then you shouldn't have much to do in configuring.  It should pretty
much work just by setting mydomain in main.cf and starting it up.

Bear in mind, every time you make a config change you'll need to run

	postfix reload

to get the changes to take effect.  (Small price to pay for having config
files that are actually legible, I'd say.)
