hi Mark

thanks for your reply

my issue is when i send a email by using sendmail commandline to mailist 
, maillist services can not read this message correctly , the message 
will become a "Message has implicit destination" warning , but it did 
have a subject and i pretty sure that i have a subject and i did not use 
cc or bcc .

this issue will happen if i speacified maillist name as the sender and 
the recipient from the comandline , that means ,if i send it from client 
, maillist service will forward it to its members as normal.
