Passbolt VS Mailcow

Passbolt - Open Source Alternative to 1Password

Here's another to add to the list, Passbolt. It is open source and basically built for teams and enterprise. It is design primarily with a unique security model which is based on asymmetric end-to-end encryption, with user-owned encryption keys and support easy cross functional team collaboration. Can it hosted on-prem or host it in cloud depending on your preference. Might be too much information and a tad bias as I work here but wanted you to have all the information as passbolt fits your requirement for business level password manager.

Fyi there is also Passbolt.

I currently switched from keepass to passbolt: https://www.passbolt.com/

I might be bias here as I work here but another recommendation would be passbolt. Open source password manager that is built for teams and businesses. You can either self-host or host it in the cloud, really depending on what you require and supports secure granular sharing of credentials with nested permission in just a few clicks. Its a solution that is built with security as a top priority. It supports asymmetric end-to-end encryption based on OpenPGP cryptography using both public-private key for encryption/decryption. No secret key is stored on the server side. Both the free community edition and the paid pro version are 100% open source.

All that said...here's my shameless plug: I work for passbolt. You mentioned you have a small team, you might give it a look: https://www.passbolt.com/ there's a community edition you can install for free on the server of your choice. I'm here and happy to answer any questions.

Have you checked out Passbolt? Its open source built for teams and organisations. Supports asymmetric end-to-end encryption, based on OpenPGP. Its on-prem or you can host it in cloud. You can either opt for the Pro/Enterprise version or the free community edition depending on what you need.

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.
