i solve this error seting my dns on extra compose file for each container like doc say:
`version: ‘2.1’
services:
    ipv6nat-mailcow:
      image: bash:latest
      restart: “no”
      entrypoint: [“echo”, “ipv6nat disabled in compose.override.yml”]
clamd-mailcow:
  dns:
    - my_ip_dns_fw
rspamd-mailcow:
  dns:
    - my_ip_dns_fw
php-fpm-mailcow:
  dns:
    - my_ip_dns_fw
sogo-mailcow:
  dns:
    - my_ip_dns_fw
dovecot-mailcow:
  dns:
    - my_ip_dns_fw
postfix-mailcow:
  dns:
    - my_ip_dns_fw
nginx-mailcow:
  dns:
    - my_ip_dns_fw
acme-mailcow:
  dns:
    - my_ip_dns_fw
watchdog-mailcow:
  environment:
    - CHECK_UNBOUND=0
  dns:
    - my_ip_dns_fw
dockerapi-mailcow:
  dns:
    - my_ip_dns_fw
`
and same on unbound to forward  queries to the same my_ip_dns_fw…. i notice this because have 3 deployments , on one of them i see the correct  record dns… so made the changes restart ct and everything ok .. maybe is too late to say on 2024 lol
