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

span style="color: #ff0000;">'ssl' => 'tls',
                'port' => 25); // Optional port number supplied
'mail.server.com''This is the text of the mail.''[email protected]', 'Some Sender''[email protected]', 'Some Recipient''TestSubject'
