An der vordefinierten ISPConfig /etc/postfix/main.cf scheint etwas nicht Rund zu laufen, ein Test hat es bestätigt.

Wenn man in einem Mailclient einfach ein Konto mit "Absendername" + "Serveradresse" und wieder gleicher "Zieladresse" angibt, lassen sich Mails (SPAMs) ohne SMTP-AUTH verschicken.

ich schau mir gerade mal verify_transport_maps/verify_relay_host OPTIONS an, irgendwo drückt da der Schuh in der ISPConfig vom Postfix/MySQL MAPS check
