/**
* 邮件发送类
* 支持发送纯文本邮件和HTML格式的邮件，可以多收件人，多抄送，多秘密抄送，带附件(单个或多个附件),支持到服务器的ssl连接
* 需要的php扩展：sockets、Fileinfo和openssl。
* 编码格式是UTF-8，传输编码格式是base64
* @example
* $mail = new MySendMail();
* $mail->setServer(\"smtp@126.com\", \"XXXXX@126.com\", \"XXXXX\"); //设置smtp服务器，普通连接方式
* $mail->setServer(\"smtp.gmail.com\", \"XXXXX@gmail.com\", \"XXXXX\", 465, true); //设置smtp服务器，到服务器的SSL连接
* $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->addAttachment(\"XXXX\"); //添加附件，多个附件，调用多次
* $mail->setMail(\"test\", \"<b>test</b>\"); //设置邮件主题、内容
* $mail->sendMail(); //发送
