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.
