Roundcube can not send mail

[wallst001]

Haven't worked on my project in a while.  Had no probs a few months ago, but today I can receive but can not send email from Roundcube.  I know I'm probably missing something simple

[26-May-2017 11:43:10 America/Tegucigalpa] PHP Warning:  mail(): SMTP server response: 530 SMTP authentication is required. in C:\HostingSpaces\wallst0011\www.1sportsfanmail.com\wwwroot\roundcube\program\lib\Roundcube\rcube.php on line 1759

You should configure SMTP in the Roundcube config.
