Hi Team,
Our current configurations are like this:
We have two SMG 8380 appliances and we have to public MX records for our email domain (example.com)
currently each SMG appliance configured to NAT with MX record for inbound and out bound email filtering.
i.e. SMG1 appliance eth0 IP address 192.168.1.1 natted with one of the MX record public IP (125.x.x.x) and SMG2 appliance eth0 IP address 192.168.1.2 natted another MX record public IP ( 59.x.x.x)
From exchange all outbound emails to will be delivered to both SMG devices in round robin fashion.
But here i have a concern of in-case if SMG1 appliance ISP goes down, all outbound delivered by exchange will be queued at SMG1 until that particular MX record ISP comes up.
Is there any solution for high availability configuration options in this scenario to achieve flow all the times (may be with virtual IP option in SMG). kindly suggest.
Regards,
Jagadeesh
