It's working!!! whee :=)
I got it!
I have the correct port. Somehow my opera and this forum does not work togeather and it keeps dropping letters from my posts.
The autentication problem was gone when I changed mail_admin to mailadmin
Now everyting works like a charm.
What about local users, such as me, postmaster etc. How do I add a local alias map so that theese users allso can recive mail?
I think they don't have to use mysql, am I right?
