magento的邮件非常的领过，但是使用起来有点复杂，下面是实用的zend机制发送邮件的简单方法，如下：

public function sendEmail()
{
    $fromEmail = "[email protected]"; // sender email address
    $fromName = "John Doe"; // sender name
 
    $toEmail = "[email protected]"; // recipient email address
    $toName = "Mark Doe"; // recipient name
 
    $body = "This is Test Email!"; // body text
    $subject = "Test Subject"; // subject text
 
    $mail = new Zend_Mail();       
 
    $mail->setBodyText($body);
 
    $mail->setFrom($fromEmail, $fromName);
 
    $mail->addTo($toEmail, $toName);
 
    $mail->setSubject($subject);
 
    try {
        $mail->send();
    }
    catch(Exception $ex) {
        // I assume you have your custom module.
        // If not, you may keep 'customer' instead of 'yourmodule'.
        Mage::getSingleton('core/session')
            ->addError(Mage::helper('yourmodule')
            ->__('Unable to send email.'));
    }
}
如果想发送html代码
则实用方法：
$mail = new Zend_Mail("UTF-8"); 
$mail->setBodyHtml($body);
