Using in Clustered Environments

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:

HKEY_LOCAL_MACHINE\SOFTWARE\SolidOak\Alligate\Settings\Verification\GreylistingServer

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 127.0.0.1:10025. 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.
