PHP Warning: Mail(): SMTP Server Response: 550Aug 12, 2003
I'm writing a form for my boss with a mailing option. He gave me the SMTP to use. However, I get the error:
PHP Warning: mail(): SMTP server response: 550 <firstname.lastname@example.org>... Relaying denied in C:websitesendMail.php on line 85
I showed him the error, he cheked the mail at the server, everything was working fine !
How can I AT LEAST check if my mailing works ? (can i use m html smtp ? How can i get it ?)
