    I followed this tutorial https://www.howtoforge.com/tutorial/perfect-server-ubuntu-16-04-nginx-bind-dovecot-and-ispconfig-3/
    very precisely, but I am not able to receive (only send) eMails on my server.

    Mail Delivery system:
    Client host rejected: Access denied (in reply to RCPT TO command)

    Code:
    /var/log/mail.log

    This can cause problems

    I spent hours reading through the forum, and only subsribed to get this out of my way.
