This article demonstrates the method for using PHP and SMTP Authentication to send mail. Below is example code.

Make sure you change the following variables:

• from: the email address from which you want the message to be sent.
• to: the recipient's email address and name. host: your outgoing SMTP server name.</li/>
• username: the SMTP user name (typically the same as the user name used to retrieve mail).
• password: the password for SMTP authentication.

Sending Mail from PHP Using SMTP Authentication - Example

<?php 
 require_once "check_the_correct_path_below/Mail.php";
 $from = "Sandra Sender <sender@example.com>";
 $to = "Ramona Recipient <recipient@example.com>";
 $subject = "Hi!";
 $body = "Hi,\n\nHow are you?";
 $host = "mail.example.com";
 $username = "smtp_username";
 $password = "smtp_password";
 $headers = array ('From' => $from,
   'To' => $to,
   'Subject' => $subject);
 $smtp = Mail::factory('smtp',
   array ('host' => $host,
     'auth' => true,
     'username' => $username,
     'password' => $password));
 $mail = $smtp->send($to, $headers, $body);
 if (PEAR::isError($mail)) {
   echo("<p>" . $mail->getMessage() . "</p>");
  } else {
   echo("<p>Message successfully sent!</p>");
  }

 $host = "ssl://mail.example.com";
 $port = "465";
 $username = "smtp_username";
 $password = "smtp_password";
 $headers = array ('From' => $from,
   'To' => $to,
   'Subject' => $subject);
 $smtp = Mail::factory('smtp',
   array ('host' => $host,
     'port' => $port,
     'auth' => true,
     'username' => $username,
     'password' => $password));
 $mail = $smtp->send($to, $headers, $body);
 if (PEAR::isError($mail)) {
   echo("
" . $mail->getMessage() . "
");
  } else {
