EteSync Server VS Mailcow

Are you / have you considered leveraging postgres' row level security for this (row filtering)? Feels like a natural fit for ensuring the right subset of data gets to the right users https://www.postgresql.org/docs/current/ddl-rowsecurity.html

E2E encryption would also be nice to have, it could be worth having a look at https://www.etesync.com/ for inspiration

A few days ago I saw some guys in this community saying that they uses https://www.etesync.com/ in order to sync contacts between Proton + Thunderbird (Desktop) + Mobile. I haven't used it yet, but I saved the link.

EteSync - Secure Data Sync (version 2.4.0): Secure, private and end-to-end encrypted calendar, contacts and tasks sync

The programs will allow me to sync both my Google and my Etesyc Contacts and Calendars. Etesync also needs Etesync-Dav installed on the desktop but that is well explained on Github.

I've been running mailcow [1] on a Hetzner cloud server for a few years and am pretty happy with it.

I have been searching for a self-hosted suite similar to Google Worksuite. I found the following: 1. Mailcow - https://mailcow.email/

Yes, I switched to mailcow (https://mailcow.email) and installed Roundcube via the excellent tutorial (https://docs.mailcow.email/third_party/roundcube/third_party-roundcube).

I've heard good things about mailcow

https://mailcow.email/

You can self host email if you really want to, but it's really more trouble than it's worth. If you do self host, you have to worry about the consequences of missed emails if your server or Internet ever goes down, and you'll have to use someone else's SMTP server if you don't want your emails to go directly to spam. The cheapest good SMTP server is Amazon SES, which I believe is $0.10 per 10k emails. I've been looking into mailcow for self hosting an email server and it seems the best way to go.

However, https://mailcow.email/ is the ONLY exclusion I make for that. As it's an all in one docker managed solution. Where the only things you have to worry about is the reputation of your mailing IP.

But its probably easier to use a dockerized container with all the mail stuff integrated and pre-setup like: https://mailcow.email/

If you're looking for a full solution that I haven't tried (due to resources) try: MailCow. Good luck.
