===============================================================                                                                         
                                                                                                                                        
QUESTION:                                                                                                                               
如何发送给多人,如何CC,BCC?                                                                                                           
                                                                                                                                        
ANSWER: (此答案由SnifferPro监听OUTLOOK发送多人邮件分析出来的)                                                                           
同一封信发送/抄送给多人,在MAIL FROM:<...> 后,多次使用 RCPT TO:<...>                                                                   
每次一个邮件地址,需要发给多少人就 RCPT TO 多少次。                                                                                     
                                                                                                                                        
在DATA里面写的CC,BCC,TO,等信息只起显示作用,与实际发送人接收人无关。                                                                 
                                                                                                                                        
CC与BCC的差别:同样都是RCPT TO指定收件人,但是邮件客户端程序,不会将BCC的收件人写到DATA要传送的数据里。
