Anti-spam |
Before anti-spam scanning starts, the addresses of the recipients and senders are analyzed against the black and white lists, which are specified on the section. Then the Anti-spam component checks the message. The Anti-spam component analyzes the contents of messages and determines whether it is spam or not according to the spam-rate value summed up from various criteria. Depending on the analysis result, Anti-spam assigns an integer number to the message. A large number means that the message is likely to be spam. You can change the threshold value that is used to detect if the message is spam in Dr.Web CMS Web Console.
