Good day!
I think that in parameter smtpd_recipient_restrictions there is an error.
Now:
smtpd_recipient_restrictions =
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unlisted_recipient,
...Has to be:
smtpd_sender_restrictions =
permit_mynetworks,
reject_unknown_sender_domain,
reject_non_fqdn_sender,
reject_unlisted_sender,
reject_sender_login_mismatch,
permit_sasl_authenticated
smtpd_recipient_restrictions =
reject_unknown_recipient_domain,
reject_non_fqdn_recipient,
reject_unlisted_recipient,
... Thanks.
