> hoards of unnecessary security features

I've witnessed first hand how incredibly necessary those security features really are.

For example, installing mail server software on either Windows or Linux is trivial.

Actually operating a mail domain of any import securely in the face of determined attackers, dumbass insiders that will click anything, and constantly changing anti-SPAM technologies and standards is a full-time job all by itself.

This is why businesses rely on Microsoft 365 or G Suite.

Outsource mailservers to competent vendors like MXRoute at near zero cost. Stop focusing on the components that are pennies per user to outsource.

You cheerfully ignored the “other employees clicking random phishing links” issue that is non-trivial to solve by simply outsourcing SMTP server hosting.

You can't fix that with managed hosting either. If you think going with Workspace or O365 fixes that then I have to wonder what businesses you've been working at in the past.
