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