    /// <summary>
    /// 邮件内容的结构定义

using System;
using System.Collections.Generic;
using System.Text;
using Jmail;

namespace TianXia.MailSender
{
    /// <summary>
    /// 通过jMail实现的SMTP发送程序
    /// </summary>

    {
        /// <summary>
        /// SMTP发送接口的Send方法
        /// </summary>
        /// <param name="message">邮件内容</param>
        public void Send(Message message)
        {
            jmail.Message mail = new jmail.MessageClass();
            mail.Charset = "gb2312";
            mail.Encoding = "base64";
            mail.From = Smtp.From;
            mail.FromName = Smtp.UserName;
            mail.AddRecipient(message.Mail, message.Name, null);
            mail.Subject = message.Subject;
            if (Smtp.Auth)
            {
                mail.MailServerUserName = Smtp.Account;

            }
            mail.Subject = message.Subject;
            mail.HTMLBody = message.Body;
