Is it possible to configure relay only to receive mail on postfix in exchange on port 587, without configuring authorization on postfix, but doing it on exchange-> ad?

Question

postfix

Good afternoon, there is postfix which is engaged in spam protection, virus checking and mail forwarding to exchange on port 25, the exchange itself is responsible for sending outgoing mail. How to configure postfix so that it works the same as on port 25, but add another 587 to it so that exchange-> ad takes care of all the authorization work. Searched in google everywhere describes the option relayhost = [mail.isp.example]:587, so that postfix does the forwarding itself, indicating the passwords for whom to do this smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd, is it possible to avoid this and make everything transparent for postfix?
