   作用:用oracle发送邮件
   主要功能:1、支持多收件人。
             2、支持中文
             3、支持抄送人
             4、支持大于32K的附件
             5、支持多行正文
             6、支持多附件
             7、支持文本附件和二进制附件
             8、支持HTML格式
             8、支持
   作者:suk
   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
