I need to change target port to internl exchange server to port 5252. MTA mode uses port 25 as normal.
Cause of reicipent filter with callout needed, this is not working on smtp port 25, cause of exchange implementation.
This have to setup on another port diffrent from port 25.
I have added a NAT rule and Firewall rule, but it is not used.
