Unable to unban IP via Mailcow Fail2Ban API

giampiddu

I’m trying to unban an IP through the Mailcow API but it doesn’t seem to work.
Using this API request (that I saw in the community):

curl -4 -X POST https://YOUR-MAILCOW-URL/api/v1/edit/fail2ban -d ‘{“action”:“unban”,“network”:“YOUR-IP-ADDRESS”}’ -H “X-API-Key: YOUR-API-KEY”

the API responds with success, but the IP is still blocked.
Am I missing something? Is there another way to properly remove a Fail2Ban ban via API or CLI?

Add content type for this check

And you payload seems to be off check

so try this

curl -4 -X POST https://YOUR-MAILCOW-URL/api/v1/edit/fail2ban \
  -H "Content-Type: application/json" \
  -H "X-API-Key: YOUR-API-KEY" \
  -d '{"attr":{"action":"unban"},"items":"YOUR-IP-ADDRESS"}'

Thanks ETNyx! I ran some more tests, since curl wasn’t working, and I found a way to unban the IP:

root@mail:~# iptables -L MAILCOW -n –line-numbers | grep 83.25.4.100

1 DROP 0 – 83.25.4.100 0.0.0.0/0

root@mail:~# iptables -D MAILCOW 1
However, it remains visible in the admin panel (fail2ban parameters). Any suggestions on how to hide it? I’ve tried various solutions, but nothing works.

I believe for UI purposes it’s cached in Redis, i would suggest to to using API instead of manipulating whit iptables on host,..

I would prefer it too but I can’t find a way to do everything via API.
