Hello

I have installed last majordomo. all works fine but I could not change
the subject .

I will  put on the subject of the mail the name of the list

I have put on the .config of the mailing list the line :

# message_headers      [string_array] (undef) <resend,digest> 
        # These headers will be appended to the headers of the posted  
        # message. The text is expanded before being used. The following 
        # expansion tokens are defined: $LIST - the name of the current
        # list, $SENDER - the sender as taken from the from line,
$VERSION,
        # the version of majordomo.
message_headers     <<  END
Subject : [$LIST]
END     


and it doesn't work

thanks to help me.
