About the white and black lists of email addresses

The white and black lists allow you to specify email addresses that you need to process in accordance with the settings that have been defined for those lists individually. For example, you can add an address to the white list and disable spam scanning for messages sent from this address, or configure deletion of all messages sent from an address that has been added to the black list.

White list of Anti-Spam addresses

The white list allows you to let in messages regardless of the current settings of Anti-Spam defined in the Spam processing settings section.

A white list can contain two types of addresses, which differ by their purpose:

• Message sender addresses. Anti-Spam lets in messages received from these addresses regardless of the current spam scan settings. Sender addresses can be defined as email addresses, email address masks, or IP addresses.
• Message recipient addresses. Anti-Spam lets in messages sent to these addresses regardless of the current spam scan settings. Recipient addresses can be defined as email addresses, email address masks, as well as user accounts or groups of user accounts for addresses within a company.

Anti-Spam can let in messages without spam scans of any type, including scan for bulk email delivery, or without scan for bulk email delivery only, depending on the settings that have been defined for the address added to the white list:

• Spam and mass email. Anti-Spam lets in messages that have been classified as Spam, Probable spam, Formal notification, Phishing, and Mass mail.
• Mass mail. Anti-Spam only lets in messages that have been classified as Mass mail.

Messages that have been received or sent undergo an anti-virus scan regardless of whether recipient and sender addresses are on the white list.

The white list is empty by default.

Black list of Anti-Spam addresses

The black list allows you to process messages that come from senders whose addresses are on the list, by applying some special actions. The application assigns the Address blacklisted status to messages from those senders and performs the action that has been specified for this status in the Spam processing settings section by, for example, rejecting such messages.

Sender addresses on the black list can be specified as email addresses, email address masks, or IP addresses.

The black list is empty by default.

Priorities of the white and black list during message processing

The application applies the white and black list to messages according to their respective priorities:

1. Records on the white list with the “Spam and mass email” scope have the highest priority.
2. Records on the black list have a lower priority than those on the white list with the "Spam and mass email" scope.
3. Records on the white list with the “Mass mail” scope have the lowest priority.

If a sender address has been added to the white list and the black list simultaneously, the result of processing messages from that sender will depend on the scope of the white list record.
