It depends on your configuration and if you're installing it in Postfix
or down the line in a milter like rspamd.
I added their query zones in postfix's main.cf in the
`smtpd_recipient_restrictions` parameter.
Generates this bounce (domain and IP have been redacted):
NOQUEUE: reject: RCPT from example.com[127.0.0.2]: 554 5.7.1 Service
unavailable; Client host [127.0.0.2] blocked using Abusix Mail
Intelligence; https://lookup.abusix.com/search?q=127.0.0.2;

does that list reject submission requests as well?
This list is generated by monitoring the behavior of hosts that
connect to our traps and our partner's mail services. It includes any
IP address that exhibits behavior specific to compromised hosts,
botnet/virus infections, proxies, VPNs, TOR exit nodes, or IPs that
are NAT'ing for these hosts. These behaviors are not expected from a
genuine SMTP client.
