etesync-dav VS Mailcow

You can download it and find instructions here: https://github.com/etesync/etesync-dav

That is where I got the package from: linux-amd64-etesync-dav on Github

etebase is an end-to-end encrypted synchronization backend that supports, among other things, tasks. I use etesync for android in conjunction with opentasks on android and etesync-dav as a caldav gateway (synchronized to thunderbird with tbsync and its caldav backend) on the desktop. The backed is rather easy to run as a container image.

There's the official EteSync DAV that works with Thunderbird. :-)

2) install this local bridge server locally on the computer where evolution is installed : https://github.com/etesync/etesync-dav

I am using etesync-dav on Linux. You have to follow this guide https://github.com/etesync/etesync-dav First, make sure etesync-dav works on your OS. Then you have to install the add-ons Tbsync and Dav for Thunderbird and enter your local dav server adress. After restarting the PC the syncing works fine for me.

I'm also using EteSync with the etesync-dav "bridge" for synchronising calendars and contacts (even though, that happens outside of ProtonMail; for me it was more important to have the sync working with Thunderbird and Android devices.

To use the etesync-dav bridge downloads available here: https://github.com/etesync/etesync-dav/releases

Use http://localhost:37358/ for both servers, your EteSync username as the username and the DAV password you got in configuration and running as the password.

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

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.
