    Accessing the Roundcube, I receive emails but when I go to respond, the error message appears
    SMTP Error (554): Failed to add recipient "myemail@gmail.com" (5.7.1 <localhost[127.0.0.1]>: Client host rejected: Access denied).

    After that, run the commands.
    > postmap /etc/postfix/sasl_passwd
    > postmap /etc/postfix/relayhost_maps
    > /etc/init.d/postfix restart

    tail /var/log/mail.log

    Where can I be wrong? How to verify this issue...
