- PreInternet01 2y agoSorry, "turning your mailer off" seems outbound-related to me, whereas DNSBLs are typically used for inbound filtering? And in 2009, filtering inbound SMTP traffic using a popular DNSBL or two was definitely effective (as was greylisting). Alas, no more. But I probably misunderstand what you're saying?
