SENDMAIL on MAC OSX Yosemite

http://www.garron.me/en/mac/postfix-relay-gmail-mac-os-x-local-smtp.html

1. Create a file to store our credentials:

sudo vim /etc/postfix/sasl_passwd

2. Add something like this:

smtp.gmail.com:587 username@gmail.com:password

3. Now run:

sudo postmap /etc/postfix/sasl_passwd

4. Prepare the postfix main config file:

sudo vim /etc/postfix/main.cf

5. Add/update these lines

    relayhost=smtp.gmail.com:587
    smtp_sasl_auth_enable=yes
    smtp_sasl_password_maps=hash:/etc/postfix/sasl_passwd
    smtp_use_tls=yes
    smtp_tls_security_level=encrypt
    tls_random_source=dev:/dev/urandom
    smtp_sasl_security_options = noanonymous
    smtp_always_send_ehlo = yes
    smtp_sasl_mechanism_filter = plain

6. Stop/Start the service

sudo postfix stop && sudo postfix start

7. Check the queue for any errors

mailq

After this setup I get the following error:
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------

What setting have I done wrong?
