  参数说明：

            p_txt :邮件正文

            p_sub: 邮件标题

            p_SendorAddress : 发送人邮件地址

            p_ReceiverAddress : 接收地址，可以同时发送到多个地址上，地址之间用","或者";"隔开

            p_EmailServer : 邮件服务器地址，可以是域名或者IP

            p_Port ：邮件服务器端口

            p_need_smtp：是否需要smtp认证，0表示不需要，1表示需要

            p_user：smtp验证需要的用户名

            p_pass：smtp验证需要的密码

            p_filename：附件名称，必须包含完整的路径，如"d:tempa.txt"。

                        可以有多个附件，附件名称只见用逗号或者分号分隔

            p_encode：附件编码转换格式，其中 p_encode='bit 7' 表示文本类型附件

                                             p_encode='base64' 表示二进制类型附件

  注意：

        1、对于文本类型的附件，不能用base64的方式发送，否则出错

        2、对于多个附件只能用同一种格式发送
