[otrs] viewing e-mail tickets in web-console

Hello! I am new user and I'm starting learn OTRS as a base software for supporting users. So I create one group "Clients" and put to it my new customer user "user". User "user" has "ro" and "rw" rights to this group. Also I create new queue "AAA" and put it to the group "Clients". Also I set up PostMaster mail account and assaign it to my queue. Next I send e-mail from user "user" to OTRS mail. User has registered e-mail in my OTRS. Admin OTRS see the ticket that have been created on user's e-mail. But when user log in to customer web-part OTRS (customer.pl) he doesn't see anything. Is it possible view all e-mail based tickets also in customer web interface? Thanks.
