Forwarding emails by country?

Question

Mail server

It is required to organize forwarding of letters depending on the sender's country!
The scheme is as follows: the visitor leaves a request through the feedback form, which is sent to mailbox 1.
From this box, depending on the country of the sender (Ukraine, Kazakhstan, Russia, etc.), the letter goes to box 2,3,4, respectively.
What software and on what system can organize this thing?

Answer 1

well, right in the code of the form, define the country and send the letters to the right place, why the heck is there some kind of idiotic forwarding?*
