Hey all - I'm relatively new to all this, but working through setting up my home server to do various things, and I'm trying to understand the best way to import old mail accounts (for example from a Google takeout) so that I can a) archive a copy of current mail coming in through ProtonMail, and more importantly b) make an archive of old emails available remotely, so that I can search for and access them from a mobile/desktop client outside of my LAN. Any help or pointing towards a tutorial here would be great, I did search around a bit and didn't come up with any instructions for importing old mailboxes. Thanks!
