    Today I noticed strange issue on my ispconfig 3 installation. After some debugging it was clear that anyone can send emails to local domains without authentication.

    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.

    Any thoughts??

    Thanks in advance.

    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.

    Th mail_accesstable has to be empty for local domains, this table is only used to restrict emails forwards with transports.
