Email SMTP godaddy

It works on my localhost where I can message and email the message to myself. 
But it's not working on the live host. 


I called them, they told me standard port is 25.
And I needed to change it to remote email under MX Entry. 

I changed          $config['smtp_port'] = '25'; instead of 465 
but it is still giving me the same errors. 

Is there any other way around this ? 
Thank you
