PAT between 2 networks on same interface

Question

Hi,
I'm using asa 5505 with 8.4(2) and have the following problem.
I have 2 Networks. each Network has it's own externel Internet-Ip and also Mail-Server.
Here is the example:
Network1:
192.168.1.0/24
Mail-Server: 192.168.1.10
External: 1.1.1.1
Network2:
192.168.2.0/24
Mail-Server: 192.168.2.10
External: 2.2.2.2
Both Networks are connectet through a routing-network to the asa
interface: routed
net: 10.10.10.0/24
Now I want a communication between the two Mailservers with their external Ip-Address.
I did a static NAT from ipnt any to int any or also from int routed to int routed, but nothing worked.
Packet tracer showed at NAT-Lookup where the externel adress of the second Mailserver is passed:
Info
Static translate Network1 to Network1
But it should show a translation from network1 to network1-external
Due to Security reasons, I cannot paste the whole config. I hope the example tells enough about my Problem.
Under 8.0 I did the same configuration with Policy-Nat and it worked.
Thanks for help

Hello Roman,
1-Are they behind the same interface?
2-Can you explain a little bit better your network? A diagram would be great
Can you try this:
Object network Server-inside
host: 192.168.1.10
Object network: Server-secondary
host: 192.168.2.10
Object network Natted-inside
host 1.1.1.1
Object network Natted-secondary_server
host 2.2.2.2
Same-security permit intra-interface
nat (routed,routed) source static Server-inside  Natted-inside destination static Server-secondary Natted-secondary_server
nat (routed,routed) source static Server-secondary Natted-secondary_server destination static Server-inside  Natted-inside
