"Hm.. how can you receive emails for your domain on your home server? What will the MX record contain?"
Debian 10 buster exim4 as an MTA with smarthost setup (smarthost is used to be a server of my internet provider, using per user authentication with password). Mails are collected by fethcmail (as daemon using /etc/fetchmail.rc) dovecot as IMAP server apache2 + roundcube This combination is working for decades, from distribution to distribution, with minimal configuration. Idea about vpn could be a working solution. OFF: I have one VPN based on pair of very old TP-LINK WR1043 between my flat in city and weekend house "dacha", based on OpenWRT and OpenVpn but I'm afraid about encryption those routers have very limited resources and quite outdated.
