It’s really more of a proxy setup that I’m looking for. With thunderbird, you can get what I’m describing for a single client. But if I want to have access to those emails from several clients, there needs to be a shared server to access.

docker-mbsync might be a component I could use, but doesn’t sound like there’s a ready-made solution for this today.

Yeah, they are ideally the same mailbox. I’d like a similar experience to Gmail, but with all the emails rehomed to my server.

I think operating at 5V input might be a technical constraint for them. Compatibility revisions for existing hardware are a lot more difficult if the input voltage is 9x higher. Addressing that isn’t as easy as slapping a buck converter on the board.

Not saying requiring 5A was the right call, just that I can see reasons for not using USB-PD.
