Hi,
I am using cisco 1720 router. I have 2 MX record register on public DNS.
When sender send email to my 1st MX record , then traffic will redirect to my mail server A.
When sender send email to my 2nd MX record, then
traffic will redirect to my mail server B.
How can I configure this on the router ?

Are both MX records resolving to two different addresses or same address ?
If they are different, you can put two static nat mappings.
ip nat inside source static tcp
ip nat inside source static tcp

My router are not using NAT, it uses public IP. So how should I configure ?

So are they still resolved into two public IPs routable to your network by your ISP ?

Need more info about your network diagram. Whether Mail servers are configured with the public IPs, or private IPs, if they are behind a firewall etc.

I have 2 x mail server A and B configured with private IP located behind two firewall A and B.
My DNS server is hosted by ISP, there are 2 x MX record ( public IP ) which is pointing to both of my firewall.
I am doing a migration for firewall and setup 2 new firewall. I want to configure my cisco 1720 router to redirect the MX traffic to the new firewall, so how can I go about this.
