first, is myown.net a domain of yours, or are you hijacking it? are you exposing domains of others? that would be really bad... second. you need to setup different hostames for the various pieces of servers you use. you'll have problems if one piece connects to another and both think they are the same "name". with postfix, use different myhostname values.
