Smart Kill Listing: Smart Kill lists enable Alligate to cache IP addresses of senders that have sent spam recently.  Using this cache, Alligate can deny connections immediately, saving bandwidth and CPU time.

 

If sender has sent at least x spams recently: Specifies the number of spams that the spammer must have sent for them to be included on the Smart Kill list.

 

Temporary Blacklisting: You can temporarily block connections from a certain IP address if they have sent email to invalid recipients within the last xx minutes. If a sender has violated the rule "Block if Recipient List..." on the blocking tab page, Alligate will keep track of their activity. You can specify how many times they are allowed to violate this policy within a certain number of minutes before being blocked. When the specified time period expires, they will be allowed to send messages again. You can also temporarily blacklist a sender if they have failed greylisting a specified number of times in a single connection.

 

information

The user defined kill list is maintained as ..\Alligate\KillList.txt. It can be updated any time and Alligate will reload it automatically without user intervention. This allows the kill list to be generated from an external source and pushed to the Alligate server periodically.

 

warning

It is not recommended that the user kill list be used for other than temporary nuisance addresses. The calculations necessary to determine if addresses are part of a subnet or net block can increase the message processing time if this list is large. This becomes more important if you do higher volumes of connections daily. It is recommended that this feature be used judiciously when necessary and not as a long term blocking solution. When processing higher volumes of daily connections in the 100,000 to 1,000,000 range, even a few milliseconds in extra processing time per message can result in higher resource usage and slower processing times.
