Postifx send DSN from different IPs

I have a Postfix email server and multiple domains, each with its own IP & Reverse DNS, etc.

The problem is that when someone sends email to one of these domains and requests a "Develivery Status Notification" (DSN), the server will automatically reply from the first IP address set on the interface (the main IP provided by the ISP).

For normal email sending, I use transport_maps with "smtp_bind_address=" so there everything is OK.

The problem is with the DSN replies only. How can I set postfix to send DSN from specific IP address ?

Thank you.
