Ich drehe mich gerade im Kreis und sehe wahrscheinlich den Baum vor
lauter Wald nicht:
ich habe hier ein Setup mit virtual mailboxes und maildrop laufen, das
seit Jahr und Tag auch völlig reibungslos funktionierte. Nun kommen seit
heute massiv Reject-Meldungen rein, weil jemand meine Domain missbraucht.
Die sind bei mir bisher im catchall-Account gelandet. Nun wollte ich diese
Mails an nicht existierende User abweisen, indem ich den catchall-Account
deaktiviert habe (was früher auch funktioniert hat).
Jetzt kommen sie aber dennoch durch:
postfix/pipe[16143]: B83E21968: to=<Nuno_donret at behrle.dyndns.org>,
relay=maildrop, delay=3.5, delays=0.97/0.03/0/2.5, dsn=2.0.0,
status=sent (delivered via maildrop service)
Ich kann mich nicht erinnern außer postfix Upgrades irgendetwas geändert
zu haben. Irgendwann vor langer Zeit hab ich mal den pre-cleanup
eingeführt, um die Header unbearbeitet an amavisd-new zu übergeben
(master.cf s.u.). Auch hier kein Erfolg, wenn ich auf die
Default-Konfiguration zurückwechsle.
Hab hin und her probiert mit myhostname (Domain rausgenommen, die noch in
virtual_alias_domains stand/steht), mydomain, virtual_alias_domains und komm auf
keinen grünen Zweig.
Vielen Dank für jeden Hinweis,
Mathias
