You need to install from source, apply the TLS patch, and then make
with
make makefiles CCARGS="-DUSE_SSL -I/usr/local/ssl/include" AUXLIBS="-L/usr/local/ssl/lib -lssl -lcrypto"
Then in main.cf add the following:
smtpd_tls_key_file = /etc/postfix/private_key.pem
smtpd_tls_cert_file = /etc/postfix/cert.pem
smtpd_tls_CAfile = /etc/postfix/CAcert.pem
More details here:

I can send you more detailed instructions for postfix 2.0.15 if you wish.
