Configure your printer to send the mails to that postfix instance. By default, I think postfix will accept forwarding mails from your local network.
You may also have to configure that postfix to relay through your "uplink" postfix - relayhost=up.link.postfix - to get mails sent out via your ISP.
I more or less finished the wiki page on configuring postfix to send and receive quite advanced email, but you can also take only the first part of this page to accomplish what you described. The page is: https://en.opensuse.org/Mail_server_HOWTO The last part to be done is about DMARC. May take a few weeks more. -- fr.gr. member openSUSE Freek de Kruijf
