Hello everyone,

this is just a friendly heads up for everyone using our RBLs through the 
public mirrors. Beginning in March Spamhaus will start to enforce the 
return codes for these three new conditions announced in late 2019: - Typing error in DNSBL Name - Query via public/open resolver/generic unattributable rDNS - Excessive Number of Queries

Rspamd already has the codes in it's ruleset, so there is nothing really 
to do except check the logs in March to see that your are not hitting on 
any on them.

Please see the article at 
for more informations

Best regards,
