Multiserver-Setup - something missing in Postfix

    we have a Multi-Server-Setup with ISPConfig and we noticed that our servers don't send mail to our Main Mail server.

    The ISPConfig-Manual there is an example for the configuration of a Postfix Sattelite System where you put the FQDN of your Mailserver into the SmartRelayHost-Field. However the Mailserver does not accept mail from this sattelite system.

    Did I miss a step in the Mailserver-Setup?

    Thanks for your help.

    Open the manual in a pdf reader, open the search function and enter 'mynetworks'. It will direct you to the place where the instructions can be found.

    thanks yes. i missed it.
    It seems like only the webserver is allowed to send mail though. What about the DNS-Server?

    DNS servers shall not send any emails. I explained that already in your other thread and that's why there shall be NO postfix on DNS servers as it is installed on the web server.
