Adding addresses to whitelist and blacklist

Email addresses belonging to people you communicate with frequently can be added to the whitelist to ensure that no message originating from a whitelist address is ever classified as spam. Known spam addresses can be added to the blacklist and always be classified as spam. To add a new address to the whitelist or blacklist, right-click the email and select ESET Endpoint Security > Add to Whitelist or Add to Blacklist, or click the Trusted address or Spam address button in the ESET Endpoint Security Antispam toolbar in your email client.

Similarly, the same process applies to spam addresses. If an email address is listed on the blacklist, each email message which arrives from that address is classified as spam.
