IP addresses or Domains included in the Ignored lists will not be tested against RBL or DNSBL, but other antispam protection techniques will be applied.

Ignored lists should contain all internal infrastructure IP addresses / domain names. You can also include IP addresses / domain names of your ISP's or external sending mail servers that are currently blacklisted by one of the RBL or DNSBL (ESET's Blackhole List or third-party Blackhole List). This allows you to receive emails from sources included in the ignored lists, even though they are blacklisted. Such incoming emails are received and their content is further inspected by other antispam protection techniques.
