使用范例：
/*
        * new sendmail() 使用GBK的默认编码发送文本信息
        * new sendmail(编码,文本还是html);
        */
        wuyu.javamail.sendmail mail = new wuyu.javamail.sendmail( "GBK", true );
        /*
        * mail.connect (smtp服务器);
        * main.connect(smtp服务器,用户名,密码); 适用于smtp认证的发信服务器
        */
        mail.connect( args[0], args[1], args[2] );
        for ( int i = 0; i < Integer.parseInt( args[3] ); i++ ) {
            System.out.print( i + "\t" );
            /*
            * main.send(from,to，cc,bcc,主题,正文,附件文件名)
            * to,cc,bcc可填写多个mail地址
            * 附件文件名为null，表示不发送附件
            */
            mail.send( "mmwy@ynwst.com", args[4], "", "", "这是主题" + i, "<b>这是正文</b>", null );
            System.out.println( i );
        }
        mail.close();
