# Securing SMTP Transport

Zend_Mail also supports the use of either TLS or SSL to secure a SMTP connection. This can be enabled be passing the 'ssl' parameter to the configuration array in the Zend_Mail_Transport_Smtp constructor with a value of either 'ssl' or 'tls'. A port can optionally be supplied, otherwise it defaults to 25 for TLS or 465 for SSL.

Example #1 Enabling a secure connection within Zend_Mail_Transport_Smtp

1. $config = array('ssl' => 'tls',
2. 'port' => 25); // Optional port number supplied
4. $transport = new Zend_Mail_Transport_Smtp('mail.server.com', $config);
6. $mail = new Zend_Mail();
7. $mail->setBodyText('This is the text of the mail.');
8. $mail->setFrom('sender@test.com', 'Some Sender');
9. $mail->addTo('recipient@test.com', 'Some Recipient');
10. $mail->setSubject('TestSubject');
11. $mail->send($transport);
