Send email using the GMail SMTP server from a PHP page

Question

I am trying to send an email via GMail's SMTP server from a PHP page, but I get this error:

authentication failure [SMTP: SMTP server does no support authentication (code: 250, response: mx.google.com at your service, [98.117.99.235] SIZE 35651584 8BITMIME STARTTLS ENHANCEDSTATUSCODES PIPELINING)]

Can anyone help? Here is my code:

<?php require_once "Mail.php";  $from = "Sandra Sender <[email protected]>"; $to = "Ramona Recipient <[email protected]>"; $subject = "Hi!"; $body = "Hi,\n\nHow are you?";  $host = "smtp.gmail.com"; $port = "587"; $username = "[email protected]"; $password = "testtest";  $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>");  } ?>

// Pear Mail Library require_once "Mail.php";  $from = '<[email protected]>'; $to = '<[email protected]>'; $subject = 'Hi!'; $body = "Hi,\n\nHow are you?";  $headers = array(     'From' => $from,     'To' => $to,     'Subject' => $subject );  $smtp = Mail::factory('smtp', array(         'host' => 'ssl://smtp.gmail.com',         'port' => '465',         'auth' => true,         'username' => '[email protected]',         'password' => 'passwordxxx'     ));  $mail = $smtp->send($to, $headers, $body);  if (PEAR::isError($mail)) {     echo('<p>' . $mail->getMessage() . '</p>'); } else {     echo('<p>Message successfully sent!</p>'); }

Using Swift mailer, it is quite easy to send a mail through Gmail credentials:

<?php require_once 'swift/lib/swift_required.php';  $transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")   ->setUsername('GMAIL_USERNAME')   ->setPassword('GMAIL_PASSWORD');  $mailer = Swift_Mailer::newInstance($transport);  $message = Swift_Message::newInstance('Test Subject')   ->setFrom(array('[email protected]' => 'ABC'))   ->setTo(array('[email protected]'))   ->setBody('This is a test mail.');  $result = $mailer->send($message); ?>
