Unhappy Problems: no SMTP with postfix on ISP-config, suse9.3 v-server

Hello friends

There is a problem, i can not solve. I badly need help, because some people have no posibility to receive mails.

I use a virtual server with suse9.2 where ISP-config is runnig. I generated some webs and users. Everything works fine, but the smtp-server.

If I send a mail to an user who exists on the server, I get a message like that:

451 4.0.0 Local error in processing
Warning: message still undelivered after 4 hours.
Will keep trying until message is 5 days, 0 hours old
It is no problem, to receive mails from the server via pop3, but neither sending an mail to any user nor connecting directly via smtp is possible.

I don't know, where to search. Everything I tried, failed.
ISP-config means, that smtp is active and port 25 is open. I don't understand exactly what the problem is. Maybe you do. I hope so.
