 * 需要的php扩展,sockets和Fileinfo。
 * @example
 * $mail = new MySendMail();
 * $mail->setServer("XXXXX", "XXXXX@XXXXX", "XXXXX"); 设置smtp服务器
 * $mail->setFrom("XXXXX"); 设置发件人
 * $mail->setReceiver("XXXXX"); 设置收件人,多个收件人,调用多次
 * $mail->setCc("XXXX"); 设置抄送,多个抄送,调用多次
 * $mail->setBcc("XXXXX"); 设置秘密抄送,多个秘密抄送,调用多次
 * $mail->setMailInfo("test", "<b>test</b>"); 设置邮件主题、内容
 * $mail->sendMail(); 发送
