Was hier auch auffällt: als transport will der smtp verwenden, was natürlich Blödsinn ist. Wenn ich mir die gleiche Ausgabe ansehe, welche mal als Vergleich mit einem Funktionierenden Empfangen (mit hash: statt ldap: ) gemacht habe, so verwendet der korrekterweise dovecot als transport.

Same old, same old: Ldap liefert eine Ausgabe, Postfix ignoriert diese. Was mich wundert, denn überall anders funktioniert es: lokale Aliases, virtuelle aliases, benutzerauthentifizierung.

Hmpf.

Und wie immer sitzt der größte Fehler vor dem Bildschirm...

Kurzfassung: Ich habe ja folgendes Script verwendet zur Ldap-Abfrage:

search_base = vd=%d,ou=domains,dc=uebergebuehr,dc=de
scope = sub
query_filter = (description=%d)
result_attribute = vd

und dem dann mittels Postmap eine komplette Mailadresse serviert.

Was ich nicht bedacht habe: Postfix liefert keine kompletten Adressen, sondern nur den Domainanteil zum authentisieren. Da dieser kein @ mehr enthält liefert %d (Domainanteil des Strings) natürlich einen Leerstring. Da ich allerdings immer mit der kompletten Adresse geprüft habe...beißt sich die Katze in den Schwanz.

Nachdem ich jetzt %d durch %s ersetzt habe klappt alles wie geschmiert.

Danke auf jeden Fall für deine Tipps, die haben mir sehr gholfen (auch und vor allem das mit dem debug_peer_list)

Sebastian

Freut mich. ☺ Soll ich dann als gelöst markieren? 😉

😳 Peinlich. 4,7k Einträge, und dann vergesse ich so etwas ... danke für den REminder.
