AUTH_REQUIRED=1 AUTHMODULES="authdaemon" ESMTPAUTH="LOGIN CRAM-MD5"

Now my clients are able to send out Emails by configuring outgoing mail with authentication.

The problem is, we cannot receive Email because even server connections require authentication.

That's what AUTH_REQUIRED=1 means.

Is there a way to turn off server authentication connections or am I missing something here?

What you're missing is that when an incoming connection is accepted, there's absolutely nothing that distinguishes a connection from a mail client, and a connection from mail server. Both are SMTP connections.

Without AUTH_REQUIRED=1, authentication is still allowed, but it's optional. Configure the mail clients to use SMTP authentication, and leave everything else alone.
