                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
