docker-mailserver: SMTP only mode - SASL error

My Docker container configuration is the following:

(...)
  mail:
    image: tvial/docker-mailserver:latest
    hostname: www
    domainname: redacted.cloud
    container_name: mail
    ports:
      - "25:25"
      - "143:143"
      - "587:587"
      - "993:993"
    volumes:
      - maildata:/var/mail
      - mailstate:/var/mail-state
      - maillogs:/var/log/mail
      - ./prod/mailserver:/tmp/docker-mailserver
      - ./nginx/certs:/etc/letsencrypt/live/:ro

    cap_add:
      - NET_ADMIN
      - SYS_PTRACE
    networks:
      - djangonetwork
    restart: always
(...)

I have also run the following commands from the instructions before starting it for the first time:

./setup.sh email add noreply@redacted.cloud noreply
./setup.sh config dkim

Here’s what I have in logs of the container after trying to send a mail from the added address above:

ubuntu@redacted.cloud:~/web_app_tracker$ docker-compose -f docker-compose.prod.yml logs -f mail

I’ve also checked if SASL auth is enabled in any case, but it doesn’t seem like so:

ubuntu@redacted.cloud:~/web_app_tracker$ docker-compose -f docker-compose.prod.yml exec mail postconf -d | grep "sasl_auth_enable"
lmtp_sasl_auth_enable = no
smtp_sasl_auth_enable = no
smtpd_sasl_auth_enable = no

Can anyone help me around this, it seems like a bug? Thank you in advance.
