Ok, then it's by design. So spamassassin/amavis will have to do.
Thanks everybody for your time and input. Really appreciate it!

I can send mail from an external source (e.g. mail client on my
notebook) to a local user (local on my mailserver) without
authentication. I'm not sure, is this by design?
By default, *any* system can send mail to a local address. Postfix
normally requires client authentication only when a client wants
to send mail to a remote address.
