People, I made several examples, being them of books or the internet and all return the following message when I run the function to send the email:
Failed to connect to mailserver at "localhost" port 25, Verify your "SMTP" and "smtp_port" Setting in php.ini or use ini_set()
Could you please explain what this SMTP is? And what I should do to make it work?
Thank you.
