Adding SSL to SMTP Script

[ShaolinF]

Hi Guys,

 

I have a mailing list that I'm using to send out emails only to discover that its going to junk, so I want to send them through gmail using smtp. But gmail requires SSL in order to use, so I want to modify the code and add ssl. I've pasted the part of the code which connects to the server, I can post the whole file per request (note its very long):

 

   /*************************************************************
     *                    CONNECTION FUNCTIONS                  *
     ***********************************************************/

    /**
     * Connect to the server specified on the port specified.
     * If the port is not specified use the default SMTP_PORT.
     * If tval is specified then a connection will try and be
     * established with the server for that number of seconds.
     * If tval is not specified the default is 30 seconds to
     * try on the connection.
     *
     * SMTP CODE SUCCESS: 220
     * SMTP CODE FAILURE: 421
     * @access public
     * @return bool
     */
    function Connect($host,$port=0,$tval=30) {
        # set the error val to null so there is no confusion
        $this->error = null;

        # make sure we are __not__ connected
        if($this->connected()) {
            # ok we are connected! what should we do?
            # for now we will just give an error saying we
            # are already connected
            $this->error =
                array("error" => "Already connected to a server");
            return false;
        }

        if(empty($port)) {
            $port = $this->SMTP_PORT;
        }

        #connect to the smtp server
        $this->smtp_conn = fsockopen($host,    # the host of the server
                                     $port,    # the port to use
                                     $errno,   # error number if any
                                     $errstr,  # error message if any
                                     $tval);   # give up after ? secs
        # verify we connected properly
        if(empty($this->smtp_conn)) {
            $this->error = array("error" => "Failed to connect to server",
                                 "errno" => $errno,
                                 "errstr" => $errstr);
            if($this->do_debug >= 1) {
                echo "SMTP -> ERROR: " . $this->error["error"] .
                         ": $errstr ($errno)" . $this->CRLF;
            }
            return false;
        }

        # sometimes the SMTP server takes a little longer to respond
        # so we will give it a longer timeout for the first read
        // Windows still does not have support for this timeout function
        if(substr(PHP_OS, 0, 3) != "WIN")
           socket_set_timeout($this->smtp_conn, $tval, 0);

        # get any announcement stuff
        $announce = $this->get_lines();

        # set the timeout  of any socket functions at 1/10 of a second
        //if(function_exists("socket_set_timeout"))
        //   socket_set_timeout($this->smtp_conn, 0, 100000);

        if($this->do_debug >= 2) {
            echo "SMTP -> FROM SERVER:" . $this->CRLF . $announce;
        }

        return true;
