[KB5956] Configure Approved (whitelist), Blocked (blacklist) and Ignored (exceptions) lists in ESET Mail Security for Microsoft Exchange
Add a domain name, email address or IP address to the Approved lists (whitelist) to prevent the ESET Mail Security spam filter from scanning those communications. This criteria is based on keywords searched in the email addresses, domain names or IP addresses.
Add a domain name, email address, IP address or country to the Blocked lists (blacklist) to have ESET Mail Security mark all communications from those communications as spam.
Add a domain name, email address or IP address to the Ignored lists to continue to scan all communications for spam except for those specific lists selected to ignore. This feature is designed to protect you from spoofed emails that take advantage of your familiarity with a certain email address.
The whitelist, blacklist and exception lists in ESET Mail Security for Microsoft Exchange (EMSX) have changed between versions 4.x and 6.x. In EMSX version 6.x and later, these options are now controlled by the Approved, Blocked and Ignored lists.
