Postfix to send my emails using
Amazom SES SMTP account.
Theres one specific email (firstname.lastname@example.org) thats is returning the error
Message rejected: Address blacklisted.
When I send the email using
Outlook, it works properly, but when by
Postfix, it refuse.
Where can I check the blacklisted emails of
Postfix and find out why it has been added?
