What is a DNSBL?
DNSBL stands for Domain Name System-based Blackhole List. A DNSBL lists IP addresses, usually those that have been observed by the list operator to send junk e-mails, that are used by applications to decrease the delivery of junk e-mails. These lists are developed by third-party entities and are not supported or maintained by pair Networks. However, we give you the option of using particular DNSBLs, which may reduce the amount of junk e-mails you receive. pair Networks allows you to enable SpamAssassin’s DNSBLs that SpamAssassin uses for junk e-mail scoring. SpamAssassin uses a scoring system to determine what e-mail is junk e-mail and which e-mail messages are legitimate.
