email

Dear all,
I have a problem with my PHP mail sending. I am a beginner with PHP.
I get this result and my email does not send:

Strict Standards: Non-static method Mail::factory() should not be called statically in C:\xampp\htdocs\phptest\email.php on line 34

Strict Standards: Non-static method PEAR::isError() should not be called statically, assuming $this from incompatible context in C:\xampp\php\PEAR\Mail\smtp.php on line 365

Strict Standards: Non-static method PEAR::isError() should not be called statically, assuming $this from incompatible context in C:\xampp\php\PEAR\Net\SMTP.php on line 450

Strict Standards: Non-static method PEAR::isError() should not be called statically, assuming $this from incompatible context in C:\xampp\php\PEAR\Net\SMTP.php on line 467

This is configuration of my PHP at Php.ini:

[mail function]
SMTP = smtp.gmail.com
smtp_port = 465
mail.add_x_header = Off

and this is my code at email.php:

<form method="post">
Gmail username: <input type="text" name="MailFrom"/><br />
Gmail password: <input type="text" name="MailPass"/><br />
Send Email To: <input type="text" name="MailTo"/><br />
Subject: <input type="text" name="MailSubject"/><br />
<!--CC: <input type="text" name="MailCC"/><br />-->
Body: <input type="text" name="MailBody"/><br />
<input type="Submit" name="submitMail" value="Submit Mail"/>
</form>

if(!empty($_POST['submitMail']))
{
    require_once "mail.php";

    $MailFrom=$_POST['MailFrom'];
    $MailPass=$_POST['MailPass'];
    $MailTo=$_POST['MailTo'];
    $MailSubject=$_POST['MailSubject'];
    //$MailCC=$_POST['MailCC'];
    $MailBody=$_POST['MailBody'];

    $MailHost = "smtp.gmail.com";
    $MailPort = "465";

    $headers = array ('From' => $MailFrom,
                      'To' => $MailTo,
                      'Subject' => $MailSubject);
    $smtp = Mail::factory('smtp',
                   array ('host' => $MailHost,
                          'port' => $MailPort,
                          'auth' => true,
                          'username' => $MailFrom,
                          'password' => $MailPass));

    $mail = $smtp->send($MailTo, $headers, $MailBody);

    if (PEAR::isError($mail))
    {
        echo("<p>" . $mail->getMessage() . "</p>");
    }
    else
    {
        echo("<p>Message successfully sent!</p>");
    }

}
