I’ve searched for ‘SBLCSS’ on the forum but wasn’t able to find how I can whitelist domains in my MiaB installation from this Spamhaus query. I have a customer that mentioned a specific domain was blocked multiple times.
In the logs it states the following: Jul 17 00:00:00 mail postfix/smtpd: NOQUEUE: reject: RCPT from <host>[<ipv6>]: 554 5.7.1 Service unavailable; Client host [<ipv6>] blocked using zen.spamhaus.org; https://www.spamhaus.org/sbl/query/SBLCSS; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<host>
How can I whitelist a specific domain? Thanks in advance!
