When using greylisting in clustered environments where 2 or more Alligate servers need access to the greylist database, it is advisable to install Alligate on a separate machine and activate only the greylist service.


To configure Alligate to use a specific server for greylisting checks, you will need to modify the following registry key:




This is REG_SZ (String) value and must contain the IP address of the greylisting server, a colon, then the port the greylisting server is listening on.


By default, this is set to This indicates that the greylisting server is running on the LOCALHOST machine and listening on port 10025.




In a clustered environment, you must maintain excluded domains and excluded addresses on the server that is running the greylist service.
