7.1.5 IP DNS Blocklist
IPDNSBlocklist checks the IP address of the sending mail server against a public list of mail servers
known to send spam. GFI MailEssentials supports a number of IP DNS Blocklists. There are a number of
third party IP DNS Blocklists available, ranging from reliable lists that have clearly outlined procedures
for getting on or off the IP DNS Blocklist to less reliable lists.
GFI MailEssentials maintains a cache with the results of queries to the IP DNS Blocklist to avoid
querying the IP DNS Blocklists multiple times for the same IP addresses. Items remain in the cache for
4 days and are cleared on GFI MailEssentials AS Scan Engine service restart.
This filter is enabled by default on installing GFI MailEssentials.
