SMTP Load Balancing
Hello,
We have an issue where SMTP load balancing does not seem to work. The SMTP virtual server consists of a pool of 4 SMTP nodes. When multiple clients connect to the SMTP virtual server we can see that the load is distributed between the nodes in the pool under the SMTP virtual server. However, when a single client connects to the virtual server one node in the pool is chosen and the clients SMTP load is not distributed to the other nodes in the pool. That being the case if a single client connects it uses 1 single node to send all the SMTP traffic that it has. In some cases the single client can send hundreds of emails using only 1 node.
Since no persistence is configured, shouldn't the SMTP traffic from the single client be load balanced between all the nodes in the pool?
Thanks,
