My b2evolution Version: 1.10.2

Hello, When I send a message by mail, b2evolution automatically does not treat the received messages. I am obliged to establish a connection with an admin connect to repatriate my message. It is possible to do it automaticly?
Because people who post message by mail don't have admin privilège, and finaly, i'm must connect with my admin privililège to repatriate each message

thank you .......
