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.
