    Could you please advise how I can disable SMTP Authentication for an ISPConfig 3 Installation ?

    Put the IP or ip range of the server or client that shall be able to send without authentication into the mynetworks line in postfix and restart postfix.

    Hi Till,
    Thanks for the reply.
    That's not what I mean though.
    I mean to stop users with a pop username and password being able to use it for authenticated SMTP on port 25.

    Edit the mailbox and check the 'Disable SMTP' checkbox.

    you can try to add "-o smtpd_sasl_auth_enable=no" to the smtp-services in the and restart postfix.
