warning: Mail(): SMTP server response issue
Hello,
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:
contactus.php
Kind regards
Jurg
