hey guys!

zone 'zen.spamhaus.org' did not respond to test point (null)

i have this message from time to time

and then "re-enabling zone zen.spamhaus.org"

is it a problem with spamhaus or is this a problem on my server? :)

r3pek: sounds like temporary DNS resolution failure from time to time.

You might be hitting a busted public mirror occasionally

How often is it happening?

Are you using a local caching nameserver?

hummm

hard to tell unfortunatly

docker swarm

Hmmm

Then I'd say this is most likely a local problem.

it points to a 127.0.0.11 in the containers

but the host is pointing to 1.1.1.1

Yeah - that won't work.

1.1.1.1 is Cloudflare DNS

yeah

Spamhaus will likely block queries from it because they can't track the origin of the queries.

that part i know :) just don't know how the swarm's dns server works

Their service is only free for non-commercial entities doing <= 3,000 queries per day.

So if you're going to use a public mirror - you'll need to use a local caching nameserver on your own network that you control.

ah ok

need to read about this docker internal dns server

maybe it's configurable somehow to cache

No - that won't be good enough.

You'll need to create another docker containing something like pdns_recursor

Then point all of your Haraka instances to it instead.

that's doable
