I have one mailbox in postfix and several aliases to it. Is it possible to create whitelists for specific alias in order to allow only the addresses from the list to send messages.
email@example.com user firstname.lastname@example.org user
I would like to permit only two users(email@example.com firstname.lastname@example.org), to send a message to email@example.com In the other hand when someone wants to send a message to firstname.lastname@example.org, No restrictions are applied.
Is it possible to configure postfix server this way?
