What needs to be done to use postfix?

Edit mailer.conf? And what calls mailer.conf?

Edit /etc/postfix/main.cf? Which binary should I be pointing at?
/usr/sbin/postfix or /usr/libexec/postfix/sendmail?

Where does mailwrapper come into the picture?

The last time I set this up on NetBSD, I just downloaded the latest source
and installed it in /usr/local. Make sure no other mailer was running, and
started it from /etc/rc.local.
