I recently set up my account and I am unable to send emails. I have not been able to find the answer to my issue. Hopefully someone can help me. Here is the error message: 

Error while processing the request! Unable to send message;Reason:530 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM

I put in the right outgoing information. However, I can not double check again, because I do not know how. Nonetheless,  I am not sure why I can not send emails out. 

Any help will be appreciated. Thanks!
