'X-Mailer: PHP/' . phpversion() . "\r\n" . "MIME-Version: 1.0\r\n" . "Content-Type: text/html; charset=utf-8\r\n" . "Content-Transfer-Encoding: 8bit\r\n\r\n"; ini_set("SMTP","smtp.xyz.com"); ini_set("smtp_port","25"); ini_set("sendmail_from"," [e-mail] "); mail($to, $subject, $message, $headers); 

Answer 1

As you can read in the PHP manual , the SMTP functionality for PHP is available only on Windows, and it has only basic functions. If you need to use it on Linux and / or require username and password authentication, SMTPS, etc., you will need to use libraries such as SwiftMailer , PHP Mailer , etc. or you need to configure an external SMTP server on your own host, for example Exim .

However, you should not try to configure the SMTP server if you have no such questions, or you will make your server a spammer socket within a few days.
