Bulb Tooltip   Load balancing using MX records

When your organization is sending and receiving a lot of emails, you would need to route inbound emails to multiple mail servers in a way that the mail servers process roughly the same amount of emails, thus load balancing the mail servers. For example, you may define 3 MX records with an equal value. This will only work provided that the 3 MX records resolve to different A records. MX 10 MX 10 MX 10

Alternatively, you may set only 1 MX record, but assign multiple IP addresses to it. MX 10 MX 10 MX 10 A
