warning: Mail(): SMTP server response issue


I copied the data over to my site and tried to run it for a test only. Once the form is submitted I get the blank form again with the following message on top of the form:

Warning: mail(): SMTP server response: 451 See smtplf.html. in D:\iftpsvc\lightning\www\WA_Universal_Email\mail_PHP.php on line 254

Warning: Cannot modify header information - headers already sent by (output started at D:\iftpsvc\lightning\www\WA_Universal_Email\mail_PHP.php:254) in D:\iftpsvc\lightning\www\contactus.php on line 35

Could you please advise on what to do? The site where I installed the form is:


Kind regards
