About lists of allowed and denied email addresses

Address allowlists and denylists allow you to specify the addresses of email messages that should be processed in accordance with the settings that have been defined for those lists individually. For example, you can add an address to the allowlist and disable Anti-Spam scanning for messages sent from this address, or configure deletion of all messages sent from an address that has been added to the denylist.

Anti-Spam address allowlist

The address allowlist lets you allow messages regardless of the current Anti-Spam settings defined in the Spam processing settings section.

An address allowlist can contain two types of addresses, which are distinguished by their respective sides in communication:

Anti-Spam can allow messages without performing any type of Anti-Spam scan on them, including mass mail scans or excluding only mass mail scans, depending on the parameters that have been defined for the address added to the address allowlist:

Messages that have been received or sent undergo a virus scan regardless of whether or not the recipient and sender addresses are on the allowlist.

The address allowlist is empty by default.

Anti-Spam address denylist

The address denylist lets you apply special actions when processing messages received from senders whose addresses are on this list. 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 denylist can be specified as email addresses, email address masks, or IP addresses.

The address denylist is empty by default.

Priorities of address allowlists and denylists when processing messages

The application applies address allowlists and denylists to messages according to their respective priorities:

  1. Records on the address allowlist with the "Spam, phishing, and mass email" scope have the highest priority.
  2. Records on the address denylist have a lower priority than records on the address allowlist with the "Spam, phishing, and mass email" scope.
  3. Records on the address allowlist with the "Mass mail" scope have the lowest priority.

If a sender address was added to the address allowlist and to the address denylist simultaneously, the result of processing messages from this sender will depend on the scope of the address allowlist record.
