Hi,
Hmm. How do I check that?
Running nslookup defaults to my local resolver instance.
you can run
host whoami.akamai.net
which responds with IP of the used resolver.

If it happens silently at the ISP's end, you can't check it - except
indirectly. What are the return codes that you get from your Spamhaus
Zen queries?

The IPs of "fonts.googleapis.com" got listed on SBL because these IPs are also
used to serve "firebasestorage.googleapis.com".
Last time i checked the IPs with https://check.spamhaus.org/ it told

This only applies if your sending more than 5000 messages per day.

OK, thanks. I did this all because of problems sending to some places
managed by Google.

If you use even a relatively modern email stack then it's quite trivial
through rspamd for example. Some have it (and more) even built-in, like

There are multiple services doing that, some even IPv6
capable, but if you know any IP which doesn't run DNS server
(or blocks it), you can do connect/syn scan to its port 53/tcp
too, if

That is a "MUST" in RFC sense ;), because otherwise they reject mails from
you.
But if you read their sender guidelines, they say since long ago (long

Doesn't matter how small your server is, or isn't. Spamhaus blocks
public queries, but does it a bit imperfectly, so it's the kind of
thing where you can get away with it for a while, then something
changes, and they find a new way to lock it down a bit better. Look
at the response code.

You definitely will if

Aside from the question in the subject, because I see this brought up a
lot on the mailing list in relation to email forwarding, would passing
ARC signatures even matter when the problem is that Google is
increasingly rejecting forwarded emails due to the DMARC policy of the
original sender

From Spamhaus documentation:
"access to public mirrors requires the use of a non-public, non-shared DNS
resolver (therefore excluding services like Google Public DNS), while DQS can
use any DNS channel"

This is not true.
One of the main points of DQS is that the DNS service you use no
longer matters. They don't need to block
