Load Balancer Configuration
We recommend load balancing via DNS records. The A records for the MX for inbound traffic can be assigned multiple host addresses and the outbound relay hostname A record can be assigned to multiple outbound servers.
The most common setup for load balancing consists of:
- A hardware load balancer communicating with the Spam Experts nodes via an internal-IP address
- The Spam Experts nodes use the load balancer as gateway for the internal traffic which handles the communication back to the source
Installation and integration of a hardware load balancer is specific to the make and model.
