Errore di configuration del relè SMTP Postfix

Per l'ultimo giorno stavo cercando soluzioni per questo problema:

La mia configuration postfix (+ wherecot) è in grado di ricevere e-mail e di servirli tramite IMAP ma non riesce ad accettarli tramite SMTP (port 587).

  • Postfix: che cosa sono esattamente i domini alias?
  • PTR OK, SPF, DKIM passato ma i messaggi di posta elettronica sono contrassegnati come spam da parte di Google?
  • Non posso visualizzare alcun registro dettagliato per Postfix in Centos
  • Esegui lo script sul messaggio di posta in arrivo al postfix
  • Graylog che non è in grado di submit e-mail (SMTP)
  • Perché il mio porto 25 è così attivo?
  • Ho già provato ad aggiungere example.net a relay_domains , ma non è riuscito come è già nel database dei domini della cassetta postale virtuale.

    Ho già provato a aggiungere mail.example.net al database dei domini della cassetta postale virtuale.

    Per il set-up ho seguito la guida di Ars Technica per la creazione di un server di posta elettronica. Forse si riconosceranno alcuni elementi. Nota: non potevo seguire la guida esattamente a causa della mancanza del pacchetto postfix-wherecot, ma penso di aver superato il problema potenziale poiché posso ricevere la posta.
    Nota ulteriormente: submit ad altri indirizzi (come webmaster@example.net) funziona.
    Posso fornire tutti i file necessari.

    Se necessario: la versione postfix 2.11.3

    Nota: example.net è la sostituzione del mio dominio. È valido, viene configurato DNS e vengono installati certificati TLS validi.

    Il rifiuto è stato causato da smtpd_recipient_restrictions . Elimina reject_unauth_destination da smtpd_recipient_restrictions dovrebbe risolvere il problema.

    Hai già messo reject_unauth_destination in smtpd_relay_restrictions , quindi non è necessario ripeterlo in smtpd_recipient_restrictions .

    Questa è la parte del tell-tale del log. Porta alla risposta di masegaloeh.
