To connect to an outgoing Smtp server from a PHP script using SMTP authentication and send an email:

• Make sure the PEAR Mail package is installed.
  • Typically, in particular with PHP 4 or later, this will have already been done for you. Just give it a try.
• Adapt the example below for your needs. Make sure you change the following variables at least:
  • 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.
  • 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 "Mail.php";
 
 $from = "Sandra Sender <[email protected]>";
 $to = "Ramona Recipient <[email protected]>";
 $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>");
  }
 ?>

 $subject = "Hi!";
 $body = "Hi,\n\nHow are you?";
 
 $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("<p>" . $mail->getMessage() . "</p>");
  } else {
   echo("<p>Message successfully sent!</p>");
