You might need to change this value in case it is struggling to reach public DNS servers and Postal shows that as misconfigured postal/config/postal.defaults.yml Line 17 in 87e9b3e |

The documentation is apparently missing that you need an MX record on the return path, in your case it would be a copy of the routes.postal one. |

I have the same problem. Any idea? Sometimes fail SPF, sometimes DKIM. The provider of DNS is cloudflare. This is my config YAML general:

The records are OK, but auto check fail... Manual check from the ui works immediately. In the server, Thanks for your help! |

Hi Will! Yes. This is the date of modif config file.
Here is the restart, before autocheck detect domain missing...
Now I'm waiting to see if the issue occurs again to review the logs once more and pinpoint the exact moment when the fluctuation happens. In the previous installation, I tried with 5 domains, and it was fluctuating randomly between them. So far in the new installation done yesterday, I only loaded 2 domains and only one has failed, with about 3 hours between when I registered the domain, validated everything properly, and then the auto check failed it. Thanks! |

Hi @willpower232 ! Yesterday fail with SPF, today with DKIM. The DKIM record really exists and was verified yesterday. This is a screenshot of record of the postal DB. This time fail DKIM check, but manual verification works. This is the screenshot of logs that match with dns verification date of domain with missing dkim record: I don't known why check time is 80sec for simple DNS query... but this is the problem, no doubt.. It's posible enable verbose log or more details in the worker container? Thanks! |

It seems everything is set up correctly as far as I can tell so I can only presume the fault lies with your servers hosting company taking a bit too long to resolve the DNS records, as you say 80 seconds is a long time. What happens if you |

We have similar issue. In our case it's around 800 domains added to one server. They will randomly fail dns check, doesn't matter if the I also have a Playwright script that goes to every failed domain and re-checks it, it never fails during the execution of this script. Since all those domains are managed in Cloudflare by us, we are 100% they are configured correctly. Disabling automatic check would solve this issue. |

Hi,
DNS verification fluctuates sometimes its shows "DKIM & SPF configured correctly on 1 domain" After some time it shows "1 domain has misconfigured DNS records". This is happening to one domain and another domain it is stable(different server). I have tweaked all DNS records, but it is still fluctuating.
I want to know whether it is a server problem or a Postal Server issue.
it would be a great help to resolve.
Regards
Maurya
