Blacklisted domains tab

This section enables the definition of domains from which analyzed messages will be systematically treated as spam.

Domain name (generic characters accepted: * and ?) Specify the domain to be blocked. Up to 256 domains can be defined.
Click on Add. The length of the domain name must not exceed 128 characters.
The added domain will then appear in the list of blacklisted domains. Messages that are treated as spam because their domains are blacklisted will have the highest level of trust (3). To delete a domain or the whole list of domains, click on Delete.

Some operations listed in the taskbar can be performed by right-clicking on the table of blacklisted domains.

NOTE
Blacklisting and whitelisting prevail over DNS blacklist analyses and heuristic analyses. The domain name of the sender is compared against blacklisted and whitelisted domain in succession.
