How to automatically change the sender when working with multiple mailboxes?

Question

Email

It is necessary that when sending a response to a letter, the sender automatically becomes the box with the signature to which the letter was originally received.
Tell me how or in which web service or client you can make such a setting.

Answer 1

Gmail for example. Everything works like clockwork for me

Answer 2

Server solutions - if you manage a mail server.
procmail - probably already outdated)))
postfix - it seems to have been alive. What are we talking about here .
For the user - any normal mail client, for example, Thunderbird. He seems to understand from which account you send the answer.
