One of my relays has been listed on backscatter.org, now I'm trying to configure our existing config only to send bounces to local users only. Does anyone knows how I deal with this issue?
I've added following rule in my acl_check_rcpt
deny senders = : dnslists = ips.backscatterer.org log_message = $sender_host_address listed at $dnslist_domain message = Backscatter: $dnslist_text
Would this be enough not get listed again?
