Verify an email address - Error: authentication not enabled

I have been following this example on how to verify an email address:

https://gentlenode.com/journal/meteor-20-verify-an-email-with-meteor-accounts/42

Basically I created a new Meteor project, and added the following packages:

email
accounts-password
accounts-ui

I then followed steps 2 to 4 to set-up the smtp configuration, meteor account configuration and send a verification email.

When creating a new account the user document is created in the database but the email verification is returning an error which I cannot find a solution to - but I am not not sure what it is trying to tell me. The only item I am unsure about in the smtp is the port number, the user name, password and server I have checked and rechecked over and over again.

When running in local host I get the following error.

It is now working - found out that the email account I was using did not allow smtp sending of emails!
