DLP Prevent won't work with load balancing?
I'm routing outbound email from a Lotus Notes network through DLP Prevent to several internet email appliances that are on different subnets around the company. In order to balance the outbound message load, we've put the appliances into a 3DNS pool - call it "outbound.example.com". For those not familiar, this means that whenever a system such as DLP is configured to use the mailhost outbound.example.com to send messages, it resolves that name in DNS and gets a different IP address each time.
Sending directly from Lotus Notes to that pool works fine - mail traffic is distributed across all of the appliances. Unfortunately, when sending through DLP, it seems to latch on to one IP and never uses any of the others. Is there any way to change this behavior?
