Please **try** to answer all questions. If you cannot, don't just delete it. If you completely ignore or remove the whole template, your issue is either closed or ignored, too. :( This is (not only) because we are evil. Many awesome mailcow supporters don't bother to reply to an issue, when crucial information is missing. Especially when it could have been answered by using this issue template. We need as much information as possible. Please post all logs, do not copy that one line you think may be interesting. Copy the whole bunch and remove sensible information. :) Thank you!
**Prior to placing the issue, please check following:** *(fill out each checkbox with a `X` once done)*
- [ ] I understand that not following below instructions might result in immediate closing and deletion of my issue.
- [ ] I have understood that answers are voluntary and community-driven, and not commercial support.
- [ ] I have verified that my issue has not been already answered in the past. I also checked previous [issues](https://github.com/mailcow/mailcow-dockerized/issues).
- All third-party firewalls and custom iptables rules are unsupported. Please check the Docker docs about how to use Docker with your own ruleset. Nevertheless, iptabels output can help _us_ to help _you_: `iptables -L -vn`, `ip6tables -L -vn`, `iptables -L -vn -t nat` and `ip6tables -L -vn -t nat `
- Check `docker exec -it $(docker ps -qf name=acme-mailcow) dig +short stackoverflow.com @172.22.1.254` (set the IP accordingly, if you changed the internal mailcow network) and `docker exec -it $(docker ps -qf name=acme-mailcow) dig +short stackoverflow.com @1.1.1.1` - output? Timeout?
