    <para>
        <classname>Zend_Mail</classname> also supports the use of either TLS or
        <acronym>SSL</acronym> to secure a SMTP connection. This can be enabled be passing the
        'ssl' parameter to the configuration array in the
        <classname>Zend_Mail_Transport_Smtp</classname> 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
        <acronym>SSL</acronym>.
