How do I set up outbound SMTP using PEAR::Mail?


The following example of code shows you how to send an email using outMail as the SMTP SmartHost mail relay using the PEAR::Mail module for php.

outMail is an authenticated SMTP relay so the example below shows authentication in php as well. The code below uses the default SMTP port 25 but it can easily be changed to an alternative SMTP port by editing the line code $mail_params['port'].

Example code smtp-test.php

  <title>SMTP Test using PEAR::Mail in PHP</title>


// set the recipients (to) address [REQUIRED]
$mail_to                 = '';

// set the mail headers which include sender address, subject, etc
$mail_headers['From']    = '';
$mail_headers['To']      = $mail_to;
$mail_headers['Subject'] = 'Test message';

// set the mail content
$mail_body               = "The test messsage is having this body line inside.";

// set the smtp mail server [REQUIRED]
$mail_params['host']     = '';
$mail_params['port']     = 25;    // Can use alternative ports if needed (See below)
$mail_params['auth']     = 'PLAIN';
$mail_params['username'] = 'outmail-username'; 
$mail_params['password'] = 'outmail-password';

// optional SMTP debug options
// $mail_params['debug'] = true;

// Create the mail object using Mail::factory
$mail_object =& Mail::factory('smtp', $mail_params);

// Send the message
$mail_object->send($mail_to, $mail_headers, $mail_body);
