There is a website, which sending email use smtp authentication only, can not use anonymous. Postfix is a mail gateway, and I don't want install a smtp authentication backend.
Will permit_mynetworks parameter ignore smtp authentication, and accept the email?

Can you provide more details on what you are trying to achieve? Generally speaking, you can use permit_mynetworks in your smtpd restrictions to exempt local clients from SMTP authentication. However, if mail submission is bound to a external (Internet-facing) network interface on which untrusted clients can connect, you definitely do not want to allow unauthenticated submission, because that would turn your mail server into an open relay. -Ralph
