I was wondering how practical it would be to run my own email server at home, I’ve set up servers before and know how to forward ports and such. Would it be possible to do it on an rpi 4 and do you guys have recommendations on any free software for setting up an email server. Thanks!

    I set it up with Postfix and it’s running rock solid for a year now. But as a newbie to email hosting, it took me months to configure DMARC, DKIM, rDNS and all that stuff. I am actually running it on a dynamic IP and relaying outgoing mails through my domain provider to avoid blacklists. Works very well for me!

    If you have a dedicated rpi4 for this, maybe you want to have a look at mail-in-a-box?

    I haven’t tried it myself, but it uses almost the same components that I individually set up for my own server…
