I would like to host an email service for around 150+ people. It's not possible for us to offroad Protonmail which focuses on security. What are the some best open source email solution available?

Postfix with Dovecot or Cyrus IMAP, along with a good sysadmin.

For 150 users you need a sysadmin. Go and hire one.

Please stop with this advertisement. Yea, we know you are a sysadmin but whether its 150 users or 1500, it's not you who is going to decide if he needs one or not.

Indeed, it's not me who decides, it's the reality that decides.
