Hi, I'm currently the following two parameters: reject_authenticated_sender_login_mismatch, reject_unauthenticated_sender_login_mismatch,
under 'smtpd_recipient_restrictions' to enforce sasl username+password authentication. As you may know, M$ Exchange, when using an external SMTP, can't send username+password of each user but only 1 username+password for all the domain. In short, postfix must allow spoofing the username of the domain. Perhaps I'm missing something about all this, if not, the question is: is there a way in postfix to disable the two parameters above just for that domain (thus allowing spoofing of the username, only for that domain) ? Thank you.
