Why in your example did Postfix treat the RCPT TO that was not a valid list address differently than any other invalid address in RCPT TO? I.e. Postfix should be rejecting that RCPT TO at SMTP time with "unknown user" or some similar error. What did Postfix do in your case.
This is probably due to an error in local_recipient_maps in Postfix. https://www.postfix.org/LOCAL_RECIPIENT_README.html
