Load balancing with RiskFilter

Once you have configured your RiskFilter cluster, you can set up load balancing using MX records:

1On the DNS server hosting your domain, create an MX record for each primary RiskFilter server using the same MX preference.

2Give the failover server a higher number. This will give it a lower preference.

Table 5-1 shows an example of MX preference assignments for load-balancing and failover using MX records.

Table 5-1Using MX Records for Load-Balancing
