Bonjour,

L’extrait des logs indique que le courriel est envoyé depuis un compte Yandex. Dans ce cas c’est le serveur SMTP de Yandex qui transfère le courriel à ton MTA (SMTP).
Cela ne fonctionne pas car ton serveur n’est pas configuré correctement pour faire du SMTP sur le port 25. Toutes les règles que tu as ajouté au service smtp dans ton master.cf empêchent les autres serveurs de transmettre les courriels au tien : en particulier l’authentification SASL obligatoire.
Tu devrais avoir (avec submission plutôt que 587):

smtp      inet  n       -       -       -       -       smtpd
submission inet n       -       y       -       -       smtpd
  -o syslog_name=postfix/submission
  -o smtpd_tls_security_level=encrypt
  -o smtpd_sasl_auth_enable=yes
…

Il y a aussi une erreur sur les règles à la fin de la ligne :
smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_rbl_client cbl.abuseat.org, permit Restrictions SMTP
