got-your-back VS Mail-in-a-Box

Got your back is the right tool https://github.com/GAM-team/got-your-back/wiki

alternatively, give them access to the user account and have them use Got Your Back ( https://github.com/GAM-team/got-your-back )

This tool from the creator of GAM will allow you to purge a mailbox: https://github.com/GAM-team/got-your-back

THe information it gives is inaccurate and it can sometime just stop. never had a good experience with it. for a couple accounts I'd go for GYB - https://github.com/GAM-team/got-your-back

GYB - gmail backup tool (I use the linux version, but it does have a version for mac).

if you don't want to spend you can also get only emails with "got your back". https://github.com/GAM-team/got-your-back

Either Google Takeout for everything, or GYB (got-your-back) https://github.com/GAM-team/got-your-back for email. You can try GAMADV-XTD3, but it can be super complex and I’m not sure if a standard account can use it or if you have to be super admin.

may i recommend https://mailinabox.email ?

I don't see why we are a long way away. At the sandstorm end, we need to get to the point, where all updates (of both sandstorm and the apps) on the user machine are automatic. Much like they are automatic on various OSes (mobile OSes in particular but also MacOS/Windows). This is not impossible if a single OS like Debian-testing is targeted.

Mailinabox [1] almost does it. They target Ubuntu stable, and upgrades are mostly silent. But they needed user intervention when Ubuntu had to be upgraded from 18.10 to 22.04, which was quite challenging.

If sandstorm can get there, then putting it into a RPi box is simple. What's difficult is helping the general public understand the importance of protecting their data, so such a product has a reasonable market.

If you have a better solution, for example a good provider who offer agency packages which allows many domains and there is no catch, for example very small disk space, then hit me right away. Otherwise, please share your experience with hosting your own mail service. I found https://mailinabox.email/ and https://www.iredmail.org/ for example, but never had any experience with neither of them.

mailinabox.email works great on a basic vps.
