Do you remember the GMail advertisement "never delete an email again"? So 17 years later, I want to move to a privacy respecting email provider, and I got myself a 27GB of old emails. I do not want to pay ~8$/mo for the luxury of having every attachment from 2014 available, I do not want to self-host a mailserver for that purpose either, and so 17 years later I come to old good .pst, only that nowadays I'd rather not lock in myself in a proprietary format, so here I am.
The solution I have in mind is a yearly read-only ~1GB sized mbox file backed up to an immutable storage, accessible from the laptop and office PC. I wish I would be able to open the mbox archives from android or nextcloud portal, but for some reason there are no such apps (Question #0: am I missing some obvious solution to access my archives from web/smartphone?).
The way to the solution splits in 3.
New incoming messages should be forwarded by gmail to the new provider of choice, let's call it for shorthand vivaldi. So the clients, TB on the PC should not check the gmail inbox at all. Replying to these messages however should be done via the gmail account. I think I can accomplish that just by configuring two accounts in TB for gmail and Vivaldi. Question #1 Is there some smarter way to manage a ghost gmail account so that I do not mistakenly reply from the wrong address?
Intermediate messages from the past ~2 years should be moved entirely to vivaldi server. I guess I can sync TB to gmail, define a rule that moves all messages newer than 1/1/2021 to vivaldi/Archive and run it on gmail/AllMail. Question #2 is it the correct way to transfer messages? How do ensure they are deleted on gmail server?
Old messages should be split into yearly local archives. It looks like the gmail account Copies&Folders/Archives feature should be useful. Question #3 How do I move the whole existent gmail web archive to local yearly mbox files and delete it from the server?
The questions might sound trivial, but the operation is rather scary and long, so I prefer to sound dumb and ask first.
