调用参考

 string mailFrom = "[e-mail]";
 string mailTo = "[e-mail]";
 string mailAccount = "[e-mail]";
 string password = "16113333mailqx";//客户端授权码
 string title = "测试发送标题";
 string content = "测试发送内容" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
 SendEmailTool.TestSmtpClient(mailFrom, mailTo, title, content, mailAccount, password,ServerType.SERVER_163_COM);
