Projects / DNS Blacklist Packet Filter

DNS Blacklist Packet Filter

DNS Blacklist Packet Filter is a Linux netfilter client that decides whether to accept or drop packets based on the results of a DNS blacklist query (such as MAPS, SORBS, or SPEWS, to name a few). One use is to filter all incoming SMTP SYN packets for spam filtering.
