EnglishError "not allowed in state 1"
"this error occurs If your “mailcow_hostname” in the mailcow.conf appears to not be an FQDN."
- Edited
esackbauer oh but have is mail.domain.xyz? and already there name “noreply@domain.xyz”
possible is nano /opt/mailcow-dockerized/mailcow.conf right?
MAILCOW_HOSTNAME=mail.domain.xyz to domain.xyz maybe?
- Edited
Kenos MAILCOW_HOSTNAME=mail.domain.xyz
That is correct, so no need to change it.
But something is wrong with your installation. Please go through the again, and check everything regarding prerequisistes and installation. In 99.99% you missed on something.
I am assuming you are running on a supported Linux version and docker/docker compose version?
And check all the logs, especially those of postfix. Does it bind to port 25?
- Edited
Yeah is linux version: 22.04 LTD use VPS and here tutorial: 
Mailcow | CloudPanel | Documentation cloudpanel.io
and how is logs check?
Ok, that looks like postfix in docker container is binding.
Logs - mailcow: dockerized documentation docs.mailcow.email
hmm possible there “ping bad addresss postfix”?
esackbauer Take time, how solution postifx?
- Edited
Well, at first you should look at postfix logs, not at acme (Lets encrypt) logs…
And please check ALL answers in my first link to the Github issue.
- Edited
esackbauer Oh lets encrpyt, but there is “cloudflare SSL”
