I’ve finally implemented our secondary exchange server. We have a debian load balancer in place. Everything appears to be working properly however it seems as if the IP Block List Providers are not blocking spam on the secondary server.
When adding a secondary, are there any additional steps to take to make sure spam does not come through?? I’ve enabled the Anti-Spam Tab for the HT under Server config. I’ve restarted the Hub Transport Service. It shows its enabled.
The spam is getting a bit out of hand so any help would be greatly appreciated.
