After some debugging it was clear that anyone can send emails to local domains without authentication.
Thats the case on every mailserver in the internet, so its not a issue. You mix up mail relaying which is secured by smtp-auth with the normal mail receiving process of a mta. If a authentication for local domains would be required, then your mailserver would not be able to receive any emails.

I checked main.cf and sow that smtp_senders_restriction pointing to mail_access table in ispconfig database. The issue is that table is empty and I'm not sure how to add record there through ispconfig interface.
Th mail_accesstable has to be empty for local domains, this table is only used to restrict emails forwards with transports.
