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:
127.255.255.252 - Typing error in DNSBL Name
127.255.255.254 - Query via public/open resolver/generic unattributable rDNS
127.255.255.255 - Excessive Number of Queries
SpamAssassin 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.
