User unknown in local recipient table

[Kalle Erlacher]

Hallo alle,

ich bin gerade bei der Einrichtung eines Mailservers, bei dem ich momentan
an den 'local recipient table' von Postfix hänge. Der Versand von Mails ist
top, der Empfang bringt immer den folgenden Fehler:

Dec  1 14:38:44 test-mail postfix/smtpd[3366]: connect from
localhost[127.0.0.1]
Dec  1 14:38:44 test-mail postfix/smtpd[3366]: NOQUEUE: reject: RCPT from
localhost[127.0.0.1]: 550 5.1.1 <juergen at domain.org>: Recipient address
rejected: User unknown in local recipient table; from=<kalle at domain.org>
to=<juergen @domain.org> proto=ESMTP helo=<test-mail.domain.org>
Dec  1 14:38:44 test-mail postfix/smtpd[3366]: disconnect from
localhost[127.0.0.1]

Prinzipiell hielt ich mich sehr nah am Buch, finde aber den Fehler nicht.
Für Hilfe bin ich sehr dankbar.

Liebe Grüße

Kalle
