How do I convince gmail to respond on Return-Path?

Question

Programming

There is the following scheme of work - the site has a feedback form, the user enters the name, text and email for communication (let it be [email protected]). After that, the server sends a letter to the server at [email protected] with Return-Path as [email protected] There is a redirect to my mail [email protected] I click answer, but for some reason gmail responds to [email protected], and not to [email protected], which is specified in Return-Path.
Here is the part of the header that comes to my mail

Delivered-To: [email protected]

How can I convince gmail to respond with Return-Path, or maybe something needs to be changed when sending a letter with a script from the site?

Answer 1

Any MUA replies to the address specified in the From or Reply-To headers.

Answer 2

Made Reply-To, doesn't work
