/sorry for latin, but i haven't cyr/

I am running a SuSE 9.1 and use postfix.
However, if I want to use a simple ipop3d, it just does not recognize USER command:
# telnet localhost 110
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
+OK POP3 v2003.83 server ready <510a.40cf1a78@localhost>
USER sergio
-ERR Unknown AUTHORIZATION state command

I guess is somehow related with shadow suite (shadow-4.0.3-191).
ipop3d was installed with SuSE (along with Cyrus witch I deactivated).
SSH is working.

Do you have any idea?

Privet!
Za prav pat mi e da nastroivam postfix, veroiatno zatova i barkam neshto. Konfigurirah main.cf no ot klientskata mashina na vatreshnata mreja samo moga da izprashtam, no ne i da poluchavam pisma. Kato chek-vam meila ot klientska mashina /IP 192.168.0.7/ pri reciving mi iska parola na usera i ne ia priema. Kato mu dam "cansel" mi dava Sever Response:'-ERR Unknown AUTORIZATION state command`.
Bezkraino shte sam ti blagodaren ako mi dadete savet kak da opravia problema-veroiatno e neshto drebno i nedogledano dobre ot men.
